The new chips are the single-core Atom D425 and the dual-core Atom D525 both of which run at 1.8GHz, representing a small step up from the existing 1.6GHz D410 and D510. Thermal Design Power remains at 10 and 13 watts, and the stated quantity prices of US$42 and US$63 is also the same as that of the earlier chips (which, however, enjoy "embedded" status). There is one notable difference: the two new chips support DDR3 SODIMM, and Intel is promoting them for home and small business network storage devices.

To put things in perspective, unlike the Atom N270 that made the netbook explosion possible and accounts for tens of millions sold, and unlike its N450 (and N455/N475) successor, the Atom "D" processors are the ones Intel targeted for "nettops," i.e. really inexpensive desktop PCs. From what I can tell, that strategy didn't pan out as there aren't too many desktop PCs that used the D410 or even the dual-core D510. Why? Perhaps desktops and notebooks are so inexpensive these days that consumers see no reason to get a machine with anything less than a "real" Intel chip (i.e. a Core 2 Duo or one of the new Core i3/i5/i7 chips). So one explanation for the new D425/D525 is that Intel is trying to salvage the Atom "D" by giving it DDR3 support, even if it's only for SODIMM, and targeting the chips at network storage systems, whatever exactly that is in real life.

A bit more commentary about the current Atom situation: there are now no fewer than ten versions of the Atom "Z" processor, ranging from the anemic 800MHz Z500 to the considerably more powerful 2.13GHz Z560. On the market side, the vast majority of Atom "Z" processor-based products we're seeing are using the 1.6GHz Z530, which, after all this time, still seems to be deployed pretty much interchangeably with the Atom N270 (there are products that offer both N270 and Z530 versions, and there are some which switched from one to the other and vice versa). In real life, I've never actually seen a product that uses the Z550 or Z560, which is odd as even the Z540 gives the one Z540 product we benchmarked (the Panasonic H1 medical market tablet) a small but noticeable performance edge over the competition).

But what about the new Atom "Moorestown" chips, a next iteration of the "Z" processors that should finally allow Intel to be competitive in the smartphone and such market? Well, apart from their announcement in May of 2010, we haven't heard another thing whereas ARM et al get all the publicity.

So it's hard to figure out what to make of Intel's Atom efforts to-date. On the one hand, there are the millions and millions of netbooks sold, but while everyone loved the low, low prices of netbooks, few were ever dazzled by netbook performance, especially in the graphics area. With the iPad showing what all can be done with a nominally much slower chip (the 1GHz A4), and netbooks getting ever closer to low-end notebooks, it's hard to see where that's headed.

Anyway, so what about Android? It's interesting to see what difference a week can make, and in this case the difference is the lawsuit Oracle threw at Google over Android. The suit is arcane and I am not even going to try to present details (it has to do with Oracle now owning SUN, which owns Java, and Android is supposedly using part of Java in a way Oracle does not approve of), but the mere fact that one 800-pound gorilla sues another 800-pound gorilla over a platform that up to that suit had almost unprecedented momentum is reason for concern. I mean, if you're a developer, you'd probably stop work and watch while Godzilla and Mothra duke it out. And while you're taking a breather, you may have time to cool off a bit over Android and realize that for now at least it's really little more than a smartphone OS, and that's it's already awfully fragmented. And also that businesses may find it difficult to trust things that come out of the current implementation of the Android App store.

This may all blow over and the two may come to an agreement, but let's realize that Oracle is in an entirely different class than SCO who a few years ago tried to claim exclusive ownership of all things UNIX and Linux. It's hard to see everyone all of a sudden stopping to make Android phones, but if this escalates, you'll see a lot of the companies that announced Android-based "iPad killers" delay their plans.

So who may be laughing all the way to the bank? Microsoft. Nothing could please Microsoft more than seeing Android derailed. Microsoft's own mobile plans are a mess at this point, at least as far as outsiders are concerned. There may at some point again be some sort of cohesive Microsoft mobile strategy and attractive product lineup, but there isn't one now. So the more time Microsoft has to communicate a clear plan and show some real products, the more likely it is to get back into the mobile game.

And HP has a dog in the race as well. HP is already the mightiest computer company in the world, and its immediate fate is not affected by what happens to Android. However, HP is also the company that fumbled away the iPAQ brand and today has essentially no presence in the mobile/smartphone market. But they bought Palm and all of Palm's cool IP, and so if there ever was a time to make a strong push for WebOS, it's now.

We'll see what happens, both with the Atoms and with Android. Who needs reality TV shows with all this stuff going on?!

As is, Android is still very much a smartphone-oriented OS. But since it is just a shell on top of Linux (Google might object to that simplification), it can very quickly be adapted to almost any platform. For example, I simply downloaded a stable version of Android, created a bootable version on a USB key, and then booted some of the tablets and netbooks in our lab with it. The hardware never knew the difference and almost everything worked right off the bat, including WiFi. Adapting touch drivers and a few other things would be very simple.

The argument against Android is the same that people use against Linux: it's in the public domain. The program you need most may have been written by some guy from Leipzig or Buenos Aires, and that guy may have decided to ditch the code and move to Nepal. The reason why Microsoft has a stable platform is because they control it all, and the reason why iPhone/iPad apps are so very cool and polished is because you ONLY see what Apple examined and approved.

So Android's (and thus Google's) challenge will be to create the semblance of a strong, unified PRODUCT called Android, something people can rely on, and not something where a poorly written manual tells you that you first need to rebuild the kernel with the -fxuOie switches turned on for the app to run. That will be a challenge.

However, none other than General Dynamics Itronix has just released a handheld running Android. That would indicate that Android may be ready for prime time. And even if it isn't, and many questions remain, there's so much buzz and there's Google behind it. That alone will give anyone who offers Android or talks Android a strategic advantage.

Oh, and manufacturers offering both handhelds and tablets/notebooks would finally have the advantage of running the same OS both on hall their platforms, and not a mobile and a full version of an OS as has been the case with Windows and Windows CE/Mobile.

I've always liked these sorts of conferences as they provide a great way to talk with executives and product managers, and see the latest lineups all in one place. So I accepted Handheld's invitation and prepared a presentation on "Trends and Concepts in Mobile Computing."

Getting flights these days is a real pain. The standard fares are outrageously high and apparently geared towards business travelers with unlimited expense accounts. I have low fare alerts for most of the destinations I potentially travel to, but those can be an exercise in frustration as those low, low fares are hardly ever actually available. I ended up paying several times the teaser fares, and that was with long layovers and a schedule convenient for the airlines, but not for me. In an era where a web page in London, Tokyo or Stockholm loads as quickly as one next door, we tend to forget how very far away those places actually are.

After landing at Stockholm's nice Arlanda airport I booked a ticket on the super-fast bullet train to downtown Stockholm, then, since it was a glorious morning, walked the 5K or so to the Elite Hotel Marina Tower where the conference was held. That was fun, though I was quite addled with jet lag, and the little wheels on my carry-on probably didn't like the cobble stone of old-town Stockholm much.

Much to its credit, the hotel let this weary traveler check in at 10:30AM, and so I took a long nap in my nice hotel room that looked like right out of an Ikea showcase. Then it was off to registration and meeting my hosts. They were all friendly as can be, and I noticed that most Swedes indeed are blond. I met Sofia, my main contact at Handheld HQ, then Jerker Hellström, CEO and Chairman of the Handheld Group, and Thomas Löfblad, not blond, and thanks to a course of study in the US possessive of less of an accent in his English than I am after 30+ years. The two welcomed the assembly to the conference, introduced the business partners, and kicked off the cocktail party mingling.

The Handheld folks did a great job making everyone feel at ease, and so I soon had interesting conversations with the mostly European attendees as well as some from as far as Australia. I found quite a few veterans of the old Husky Computers that was later bought by Itronix -- not surprising, as I learned, since the privately held Handheld Group had once gotten its start as the Scandinavian representatives of Husky. I got a chance to meet Daniel Magnusson and Nina Hedberg of RAM Nordic AB, which had the patented RAM Mount solutions on display; the Sacci folks with their numerous bags, harnesses and other clever ways of carrying around and using handheld computers; SIGMAX with their law enforcement and ticketing solutions; Brodit with their very clever mounting solutions; I got a demonstration of the impressive mobile device management solutions by The Institution, and spent time with all the other cool stuff there. I also had a chance to finally meet the HHCS Handheld USA team, including Mike Zelman, Dale Kyle, and my ever-helpful contact, Amy Urban.

Given the 9-hour time difference compared to California, I slept remarkably well and woke up refreshed and ready for a day of conferencing. CEO Hellström gave an overview of the company, its total and exclusive dedication to rugged computing, and its pride in being the fastest growing IT company in Sweden (Handheld actually grew during the difficult year of 2009). Hellström described Handheld's "virtual production model" where the company's engineers generate specifications and design, then have the products made by a production partner, and launched either alone or with a partner. He highlighted the company's products and special solutions, as well as the newly introduced Algiz 7 rugged tablet.

Following was an excellent presentation by David Krebs, who is the director of mobile and wireless research at VDC and a frequently quoted authority on all things mobile as well as a compatriot who grew up a few short kilometers from my original home in Zurich, Switzerland. David described the current mobile technology market as "in a state of rebound" after a serious setback in 2009. He pointed out that technology penetration in many mobile areas is still only 20, 30 or 40%, leaving plenty of potential opportunity, and predicted annual handheld revenue growth of 7.5% through 2014. David also highlighted the significant advantage of rugged versus non-rugged handhelds and tablets in terms of failure rates, resulting in substantially lower TCO (total cost of ownership), certainly a big selling point in the road to recovery.

I had decided to go out on a limb and run my presentation on my iPad via Apple's iPad dock-to-VGA adapter. This worked just fine, using Apple's US$9.95 iPad version of Keynote, which is Apple's equivalent of Powerpoint. In my presentation I discussed some of the concepts and trends in mobile computing, ranging from processors, to outdoor viewable displays, to digitizers, operating systems, and emerging new technologies. Murphy's Law struck when, stunningly, the frame of my reading glasses broke right in the middle of my presentation, forcing me to continue using one hand holding up my gasses and the other hand to operate the iPad. Fortunately, I had a clip-on mic or else I'd have needed a third hand.

After that Thomas Löfblad discussed the Handheld Product line that by now includes over a dozen state-of-the-art handhelds and tablets, as well as printers and accessories. All of the newer products are carrying Handheld's own Algiz (tablets) and Nautiz (handhelds) brand names.

After lunch, Mr. Hellström discussed the product roadmap for the year ahead, with the full rollout of the newly introduced Algiz 7 tablet, a second generation Algiz 8, and a glimpse at an upcoming new product that will extend Handheld's line into a new class of devices. The company took the opportunity of the partner conference to get feedback and commentary on the new form factor, the proposed features, functionality and price.

After face time with the new product, we heard about Handheld's plans on moving forward. Sofia Löfblad talked about how the company can support its partners with case studies, advertising support, loaners, product reviews, a special support website, and several other programs. Service and Support Manager Max Dahlbom then did a humorous, energetic presentation on service, warranty, care levels and support, all geared towards helping and supporting customers and stressing the importance of good service as a differentiator. Thomas Löfblad then addressed issues such as the impact of the weak Euro, the company's MaxFreight service, insurance issues and also some product updates.

The final presentation came from Dean Lindsay, a motivational speaker and best-selling author (everyone attending got a copy of Dean's highly recommended book "The Progress Challenge") who, engagingly and entertainingly, talked about common sense concepts of attracting and fostering business and sales.

What followed was an absolutely delightful four-hour cruise of the Stockholm waterways aboard the M/S Riddarholmen. We were greeted onboard with champaign, GPS-equipped Algiz 7 tablets were mounted in several locations and provided mapping and navigation data, food and drink were delicious, as was the varied scenery passing by.

There was again ample opportunity to mix and mingle, compare notes, and talk with people from the Handheld Group as well as partners and customers. The weather played along with bright sunshine all conference long (which apparently no one expected), and then some dramatic clouds at dusk. Unusual for those of us not living in northern latitudes, it didn't really get dark until way late into the night, and daylight remained even after we got back to the dock at 11PM.

I missed out on Stockholm sightseeing the next morning as I had to grab a cab to the airport for my trip back to California. Long though the flights back were, and the 8-hour layover at Chicago O'Hare, it gave me an opportunity to reflect on a side of business we often forget or take for granted, the people side. There are lots of great products out there, all able to do amazing things. But it takes people with vision and drive and competence to form companies that can pull it all together, picking a lineup of compatible products for a well-defined purpose, then marketing, selling, supporting and servicing those products. In the end, that's what it's all about, dealing with people you know and trust, folks who've been there and will be around, and who know their business. That's the impression I got from the Handheld Group. Good company, good people.

Anyway, Sprint is now making noises about 4G and you can actually buy 4G smartphones using the Sprint network. Since Sprint is a bit in the ropes, being first may not mean all that much, but it's still good to know how things developed and where they are headed.

A couple of years ago, a product manager from one of the rugged computing manufacturers asked me what I thought of WiMAX. At the time WiMAX was a buzzword for really fast next generation wireless. I told him it was probably too early to worry about it and it wasn't clear what would happen. This is still true in 2010, but WiMAX is now available as "Sprint 4G" though technically it's the same network as the CLEAR brand name 4G network from a company named Clearwire.

Who's behind Clearwire? None other than Craig McCaw, the trailblazer who once compiled McCaw Cellular and then sold it to AT&T in the early 1990s. Where does Sprint fit in? Well, McCaw and Sprint both owned spectrum in the 2.5GHz (in fact, they own almost all of it) and decided to pool resources, with Sprint making additional investments until they were the majority stockholder of Clearwire.

Does this mean it'll be clear sailing for Clearwire/Sprint in the emerging 4G arena? Not really. Problem is, this time both AT&T and Verizon are backing an alternate 4G technology called LTE, which stands for Long Term Evolution (how do they come up with these terms?!). LTE uses the 700MHz band and physics dictate that waves in that spectrum can go farther at lower power levels and also have less trouble being received in buildings. This potentially means that LTE, in addition to being backed by the two largest wireless providers, also costs less to deploy.

For now, Spring and Clearwire claim that their 4G WiMAX network allows mobile download speeds of 3 to 6 mpbs with speed bursts over 10 mbps, and upload up to 1 mbps. Sprint and Clearwire sell both 3G/4G Mobile Hotspots (made by Sierra Wireless) and 3G/4G USB modems that look like standard USB memory keys. Clearwire offers unlimited usage for US$40/month plus a small lease fee for the modem (you can also buy it). That sounds like a good deal, but for now the map for that is quite limited.

More speed is exciting, but at least based on my various devices that use 3G, I'd be thrilled to have reliable 3G coverage wherever I go before I jump to 4G.

So what is vPro all about?

vPro is an Intel technology platform that allows remote access to a PC regardless whether the computer is booted up or the power is even on. It is intended to allow remote management, monitoring and maintenance while maintaining strict security measures. While vPro componentry needs to be included in the processor, it's a platform rather than just a technology feature, one that requires a combination of chip, board, firmware and software. vPro also includes other Intel technologies such as Intel AMT (Active Management Technology), Intel Virtualization Technology, Intel's TXT (Trusted Execution Technology) and, of course, a network connection.

While remote access and management of PCs is commonly available through software such as VNC, VNC alone may not be capable and secure enough for all corporate purposes. With vPro, VNC can still be used, but it is now the Intel AMT part that facilitates secure communication with the PC, and in conjunction with the whole vPro platform, it is not only possible to control a remote PC, but aso to start it up and—even more amazingly—log in and perform certain function even if the OS is corrupted or missing. That's because the vPro engine/platform is available at a very low system level.

How can such vPro-based remote access be used? Well, there could be a system where dispatch sends job requests to a mobile computer in a filed office or a vehicle. The request will boot the computer if it is off, and then either perform a job or prompt an operator or driver to do the job and report back. It can then turn off the computer remotely, even shut down the OS. As long as the computer still has power, it remains remotely accessible (remotely waking up a PC is usually done via a hardwire LAN connection.

Panasonic highlights vPro in the recent introduction of its Toughbook 31 rugged notebook that use the vPro-enabled Intel Core i5 processor. Panasonic even features a video that shows the use of vPro technology between a dispatch with a vPro console and a Toughbook-equipped service truck. It demonstrates how the remote console can wake up the Toughbook, run a job, then shut it down again.

Motion Computing, too, stresses the advantages of vPro in their announcement of the upgraded Motion C5v and F5v tablet PCs, stating that vPro technology will enable their customers to experience enhanced remote management capabilities so IT can secure and/or repair a tablet from any location, even with power off.

So that's vPro, a set of technologies way to remotely access and control computers securely. While remote access and control is not new, being able to do it securely, and with power down and no OS booted can definitely come in handy. Not everyone will need or use vPro, and setting things up for remote access and management is not entirely trivial, and so most users will simply enjoy the very significant performance increases of Intel's latest Core i5 and i7 processors.

"Silverthorn" and "Diamondville"

The Intel Atom processors have been around for over two years now. Initially, Intel launched two different product lines, the Z5xx "Silverthorne" processors geared towards mobile internet devices (MIDs), and the N2xx line of "Diamondville" processors for standard low cost PCs and netbook class devices.

The Z5xx versions of the Atom processor had a 13 x 14 mm package footprint and used the also new “Poulsbo” System Controller Hub. The processor had about 47 million transistors—more than the original Pentium 4. Bus frequency was 400MHz or 533MHz, and the Thermal Design Power (TDP) was between 0.85 watts for a low-end 800MHz chip, and 2.65 watts for a 1.86GHz Z540 version. The chipset used about 2.3 watts, which meant total CPU and chipset consumption wasn’t even 5 watts, far less than any of Intel's standard mobile processors. And the chipset had hardware support for H.264 and other HD decoding (but required the appropriate codecs to take advantage of it!). However, as the combo was targeted for internet devices, there was only PATA and no SATA support, though SATA could be added.

The Atom N2xx "Diamondville" family, released a bit later, was very similar to the Z5xx, so much so that to this date, I've yet to find someone who can convincingly describe why a manufacturer would pick one or the other, or what truly differentiates the two families. The Z2xx was a bit larger, measuring 22 x 22 mm, and the most popular model—the 1.6GHz N270—also had a, for Intel, very low Thermal Design Power of just 2 watts. The N2xx processors did not come with a newly designed chipset, but used lower power versions of the standard Intel 945 chipset and a separate ICH7M I/O chip. There was no HD decoding or hardware acceleration, but the chip did support the SATA interface.

The initial Atom processor families did not use two cores for cost and power conservation reasons. Instead they used Intel’s older HyperThreading technique that can process two threads, yet increases energy usage by only about 10%. Intel also developed a more power-efficient bus and a cache that could be disabled when it was not needed. The Atom Z5xx further used a new "Deep Power Down" C6 state, and similar advanced power management was available in the Atom N2xx.

What happened next was interesting. While Intel probably had high hopes for the Z5xx chips in the emerging "mobile internet device" market, it was the "Diamondville" processors, and more specifically the 1.6GHz N270, that almost singlehandedly created the new category of "netbooks" (well, the term had been used before, but never to describe a separate class of mobile computers). Despite the N270 chip's modest performance, consumers bought millions and millions of those little netbooks, most likely because of the low price that made netbooks an impulse buy as opposed to spending more for a "real" notebook computer.

The N270, however, was the sole bright spot in the Atom lineup on both sides of the Atom family, as neither the desktop-oriented N230 nor the entire mobile internet device Z5xx family did much of anything. The Z5xx chips were used in some industrial products like computers-on-modules, small form factor CPU boards, industrial tablets (such as the Handheld Algiz 8, the Mobile Demand T7000, the Logic Instrument Fieldbook, or the WinMate I980), MCAs (such as the Panasonic H1 or the Advantech MICA-101), or clamshell UMPCs (such as the Fujitsu UH900), but by and large there seemed no truly compelling reasons to go with Silverthorne.

"Diamondville" gets a little boost

On the Diamondville netbook side, the problem with the Atom N270 was that despite being used in all those netbooks, it was barely powerful enough to drive even those small, inexpensive computers. Anyone trying to do video or games on a netbook came away sorely disappointed. As a stop-gap solution, Intel released the very slightly more powerful N280 (1.66GHz clock speed instead of 1.6GHz) for netbooks, and the dual-core N330, which was really a dual-core version of the little-used desktop N230. With Atom video performance lagging, NVIDIA came up with the NVIDIA Ion Graphics chipset that was supposed to work better with Atom N-Series chips than Intel's own chipset, but it didn't come in time to make it into any of the first generation netbooks.

"Silverthorne" gets tougher

For embedded computing, in March of 2009 Intel quietly expanded the Z5XX platform with larger form factor versions that carried a "P" in their name, and then a special "large form factor with industrial temperature options" version marked with a "PT." This added the Atom 1.1GHz Z510P and 1.6GHz Z530P as well as the 1.1GHz Z510PT and 1.33GHz Z520PT. The P and PT versions used a larger 22 x 22 mm package (which is the same size as the N2xx chips) that used a different "ball pitch"—the spacing of the little balls of solder that replace pins on the underside of these tiny processor packages. That was probably done because the 0.6mm ball pitch of the original Z5xx series required high density interconnects (HDI) on the printed circuit boards, and those are more difficult to do and also more finicky, not what you'd want in the kind of rugged devices the chips were actually used. As far as temperature range goes, 32 to 158 degrees Fahrenheit is considered "commercial," whereas -40 to 185 degrees Fahrenheit is considered "industrial." Interestingly, only the "PT" series processors support the industrial temperature range; the "P" series versions are listed with the same commercial temperature range as the initial chips.

RuggedPCReview's assessment in 2009 was that "the moral of the Atom story is, at least for vertical market manufacturers: pick an Atom chip that Intel is likely to support for several years, and make certain the drivers are fully optimized and all the power saving features are fully implemented. Atom can deliver superior battery life and acceptable performance, but manufacturers must carefully target those products so customers won't be disappointed. We've seen Atom-based machines that use hardly less battery power than devices with much more powerful processors. That won't do. And we've seen some where non-optimized graphics drivers made the machines painful to use."

"Diamondville" begets "Pinetrail"

In December of 2009, Intel announced the next generation of Atom processors, or really the successor of "Diamondville." The new "Pinetrail" generation of Atom processors included the single core N450 (heir to the N270) and, adding yet another letter class, the single core D410 and the dual-core D510, both meant for low-end desktops. The big news here was that Intel reduced the chip count from three to two by integrating the graphics and memory controller into the CPU itself. The old ICH7M I/O controller chip was replaced with the Intel NM10 Express. That meant fewer chips to mount, somewhat lower power consumption, and—not mentioned by Intel—one less reason to seek third party chipsets such as NVIDIA's Ion. Reducing the chip count from three to two was nice, but the Z-series processors already had that. Graphics seemed somewhat improved, but not enough to make a huge difference, and there was still no HD playback hardware support. Our assessment was that we could not "help but feeling that Intel looked out for itself more than adding compelling value for consumers."

So for now, the N450 and the slightly faster 1.83GHz N470 are taking care of the netbook market, but what of the ever more important MID and smartphone market that Intel tried to address with Silverthorne? By now it was very obvious that Silerthorne had zero impact on that market and no one was going to base a smartphone or anything like it on an Atom Z5xx chip. Intel might have suspected as much, as even in the early days of Atom, their roadmap included codename "Moorestown," a system-on-a-chip platform.

Silverthorn replaced by "Moorestown"?

Well, Moorestown was officially introduced on May 4th, 2010. It includes the "Lincroft" Z6xx series of Atom chips, the "Langwell" Platform Controller Hub MP20, and the "Briartown" Mixed Signal IC (yes, Intel loves its code names). In its press release, Intel mentioned "significant power savings while increasing performance" in a design scalable across a range of devices including "high-end smartphones, tablets and other mobile handheld devices."

So what does Intel promise for the Z6xx platform? Nothing very specific as of yet. Power "breakthroughs" include much lower power consumption at idle and with audio active (i.e. music playing), and 2-3X reduction while browsing or playing video. That's good. Intel also promised a full 1080p video experience (really already possible with the Z5xx chips, albeit perhaps not "full"), with clock speeds up to 1.5GHz and low-power LPDDR1 memory for smartphones and 1.9GHz and faster DDR2 memory for tablets (current Z5xx series chips range from the 1.1GHz Z510 to the 2.0GHz Z550. Intel highlights that the new chips result in greater than 40% reduction in package area and a greater than 50% reduction in board area for the Z6xx and MP20, so their combined package real estate is less than 400 mm2, and the board area required less than 333 mm2. The new "Langwell" Intel Platform Controller Hub MP20 has a package size of 14 x 14 mm (same as Apple's A4) with a 0.5mm pitch and uses 65nm technology. That's down from the 22 x 22mm Poulsbo. The Z6xx chip itself is also on a 14 x 14mm package (see below).

From an architecure standpoint, the new 1Z6xx CPUs integrate a lot of the functionality that used to be part of the Poulsbo chipset, such as graphics, decoding/encoding, memory controller, etc., leaving the "South Complex" "Langwell" chip to concentrate on I/O. The graphics core integrated into the "Lincroft" CPU is the same as that on the older "Poulsbo" chip, but the core can now run at up to twice the frequency and has been optimized for power and performance. Video decoding remains the same, but there's now 720p H.264 and MPEG4 encoding and also H.263 videoconferencing encoding. Intel says that 3D graphics performance should double.

The "Briertown" "Mixed Signal IC" is meant to integrate components such as audio, touchscreen, voltage regulator, display and comms drivers and such. Intel stressed that it will be available from mutiple sources (such as Freescale, Maxim and Renesas).

While more performance was desirable, less power consumption was essential if the new chips are to have a chance in the device market. So Intel did some major work on power states. Instead of the older system-wide power management, much greater power savings are now possible by giving each subsystem its own power management capabilities. So whenever any part of a "Moorestown" system is not needed, it's turned down or off. Intel refers to those savings mechanisms as "power islands" on both the MP20 hub and on the Z6xx chip and it's all done with an involved combination of software, hardware and firmware features. The sum total of all this is that the three chips that make up the Moorestown platform combined use less power under load than the first gen Menlow platform did when running idle.

That's impressive, but also necessary. What Intel envisions for Moorestown-based devices is a range of form factors, from smartphones to sleek tablets with 10 days standby, two days music playback, over five hours of video, multi-tasking/multi-windowing/multi-point video conferencing, 1080p playback and 720p recording, and and "PC-like" internet.

With Moorestown Intel is clearly taking another run at a market where it is simply not represented. Apple has set the bar for smartphones and tablets very high, and really nothing less than the kind of performance and battery life found in Apple products will do. The performance of current Atom-based systems, those assisted by NVIDIA chips not included, ranges from perfectly adequate to rather anemic, especially with video. It's Moorestown's task to potentially change that.

NVIDIA likely won't be happy. Just when the first Atom N450/N470-based nebooks with its Ion graphics appear on the market, Intel throws another curve by including graphics into the very processor of the next generation of "internet device" Atom chips.

For embedded systems and rugged/vertical market systems developers, the ongoing fragmentation of the Atom platform into two families, and the rapid obsolescence of the two most frequently used chips (the N270 and the Z530) is also not very good news. While more performance is always better, if the Moorestown platform turns out to be that much quicker and more economical, then products based on the older chips will have suddenly become a lot less desirable.

Now what?

As far as the future of Moorestown for smartphones and mobile internet devices goes, Intel will not only have to overcome ongoing confusion about their two Atom families, but it will also face formidable competition from the ARM processor architecture camp. That includes Nvidia's Tegra, the Qualcomm Snapdragon, TI's OMAP and others.

And then there is Apple. The iPad's A4 chip, also ARM-based, is Apple-only and thus not direct competition, but with the iPad Apple has shown what is possible with a tiny processor running at just 1GHz. The iPad is uniformly seen as an excellent performer with very quick browsing and excellent video playback. The iPad does not only not need a fan; it simply never warms up at all, not even after runnning video for hours. And with the iPad's ability to run video for ten hours or more, Intel's set goal of "over 5 hours" of video looks modest at best.

So Moorestown has a great deal to prove, and Intel has a lot to lose. If the platform succeeds, the N-Series branch of the family will suddenly look quite obsolete, which will require another tweak. If it fails, Intel's reputation of being behind in mobile chips will be confirmed yet again. No one's ever counting Intel out, but Atom, netbooks notwithstanding, has been a struggle.

As a former print publisher, I spent some time comparing different approaches to magazine publishing on the iPad. Given the amount of hype about the iPad being the savior of publishing, I am surprised there is not an iMagazine app or some such. I mean, Apple could take the lead here yet again, creating the iTunes of the magazine world.
 
As is, everyone's doing their own thing, with Zinio, of course, having the lead with its hundreds of electronic titles. Problem is, they're not doing a thing different for the iPad. The PDF versions are faithful 1:1 equivalents of the print mags and it all works well, though a slight lag until each new page snaps into focus is annoying. And I am NOT willing to fill out long, cumbersome forms with address and credit card info to subscribe to a mag when it should all be 1-click.
 
Time Magazine rolls their own, for now at the absurdly high price of $4.95 per issue. Their approach is sort of a hybrid between PDF and web design and totally new stuff. It's very innovative, but takes some time getting used to. On the other hand, there really is no need to simply transform print to screen, even if it's print retrofitted with electronic stuff (links, video, forms, etc.). 
 
So Time is experimenting. Pictures that may be tiny in a magazine due to space constraints can be large, with text below it and you need to scroll down. When you zoom in to make text readable, pictures don't necessarily zoom with it; they don't need to. And how cool is it to have a full-page portrait of Lady Gaga or Bill Clinton and when you rotate to landscape, it becomes flawless high-definition video and they speak to you.
 
The iPad brings us another step closer to electronic publishing, a big one. But for now, no one is taking the definite lead. With the iBooks app and iBook store still a million miles behind Amazon, Apple probably has its hands full with filling in the many blanks, and an iMag app and store may not come to pass anytime soon, or ever. So Zinio and others have a window of opportunity, but it'll take more than selling individual mags for US$4.95 (Time) or making people put up with lag and an antediluvian 20th century style signup (Zinio).  

There are, however, exceptions. If a manufacturer claims their product can be dropped from four feet without damage, we may try that. And if a product is advertised as being waterproof, we may check that claim out as well. And this is where it gets interesting.

Most rugged products have an ingress protection rating in their specs. If the IP code system is used, as defined by international standard IEC 60529, then the second number in the code indicates protection against water. An IP67, for example, means that the product is totally protected against dust (that's the "6"), and also protected against immersion into water down to one meter (3.3 feet) for up to an hour. IP68 means protection against continuous immersion, as specified by the manufacturer.

So are there mobile computers that are waterproof? The answer is yes. There is a small, but not insignificant number of systems, primarily handhelds, that carry IP67 ratings. And the marketing for those systems often includes pictures or videos of full immersion. At trade shows you sometimes see waterproof handhelds or tablets sitting in tanks, running video to show that they are, indeed, alive and unharmed.

Now it is abundantly clear that even machines that carry IP67 ratings are not dive computers and that few will ever even be immersed in water. However, given their intended use, they MAY fall INTO water, just as they may fall off a speeding pickup truck and get stepped on. Hence our occasional testing of the stated design limits and a bit beyond.

That said, as a certified scuba diver with a good degree of experience, I've come across some pretty fascinating underwater electronics that are sealed. Diving is really interesting in that pressure plays a huge role. Each 33 feet of sea water (or 34 feet of fresh water) adds one atmosphere, or 14.7 psi, of pressure. You'd think that divers get crushed down at 100 feet, but that's not so because the human body is mostly water anyway (60-80%, depending on the individual), so all we have to worry about are the air spaces inside of us (lungs, sinuses, ears, mask mostly). We equalize pressure by breathing in pressurized air that perfectly counterbalances the water pressure. The result is that even at substantial depth, your dive mask doesn't leak at all; the flimsiest of seals will keep water out as long as there is no pressure difference and as long as there is indeed a seal that keeps air and water apart.

This means that, theoretically, if there were a way to dynamically pressurize the inside of a rugged computing device, even very delicate seals (like the very thin silicone skirt of a dive mask) would be enough to keep water out even at great depth. Now obviously, no one is about to put automated compressed air pressure equalization systems into a handheld computer; that is not what such devices are for. It's interesting, though, to examine how underwater electronics ARE sealed:

- Most underwater cameras use special housings that still allow access to the camera's controls. They usually have one big O-ring seal for the housing clamshell, and then individually sealed pushbuttons.

- Recently, an exceedingly simple waterproofing method for cameras has come on the market. It simply consists of a sealed bag of clear plastic with a lens in it. It isn't protecting against pressure, but it sure keeps the water out.

- Dive computers (the ones that compute nitrogen loading, depth, dive time, remaining time, etc.) are sometimes oil-filled. Since oil cannot be compressed, there are no pressure issues.

- There are a number of waterproof cameras now that can handle up to 33 feet of water. Examples are the Olympus Tough series, the Canon D10, the Panasonic TS2 and more. We've tested most of those down to 50 feet, and had one down to 77 feet. Those are regular cameras with LCDs, battery and I/O compartments, and numerous controls. So it might be interesting for rugged computer engineers to take one of those cameras apart and see how they do it. (Btw, LCDs sometimes get compressed so that the image is temporarily impacted, and sometimes buttons are pushed in from the water pressure).

What does all this mean for the waterproofing of rugged mobile systems? Mostly that a good understanding of pressure and sealing is required to design reliable waterproofing. Apart from the fairly complex issues of pressure, there's also a good deal of common sense. Keeping things as simple as possible is key. In a setting where ANY failure can be fatal to the equipment, it only makes sense to keep the potential points of failure as few as possible, and as simple as possible. It is not surprising that NASA has always been big on the concept of "fail-safe," i.e. systems that if they failed they failed so as not to jeopardize the larger purpose, such as survival of astronauts. Likewise, scuba regulators are designed so that if they fail, they free-flow rather than shutting off air, thus giving the diver a chance at survival.

The conclusion is that the key to waterproofing of rugged computing systems is keeping things as simple as possible. This means keeping openings to the inside at a minimum, providing double protection whenever possible, and designing things to be as fail-safe as possible. Whatever seals there are must be totally reliable; resistant to twisting, ripping or falling out; durable; and easy to procure and replace. Seals should also be noticeable so users can see if something is amiss (we once failed to notice that a black O-ring in a black housing was missing, with nasty consequences). Rule #1 though is that the less there is to seal, the better.

Well, third party to the rescue. And it's not nVidia (though that company's Ion technology will certainly improve the dire Atom platform graphics situation so that it becomes at least bearable). No, it's Broadcom which offers an inexpensive add-on card that can transform virtually non-existing Atom high-def decoding into something respectable and quite useful.

The Broadcomm "Crystal HD" High Definition hardware decoder BC970012 with the Broadcom AVC/MPEG-2/VC-1 video/audio BCM70010/BCM70012 decoder chipset is a PCIe Mini Card designed to allow full high definition real-time decoding for hardware that otherwise could not do so. The board can decode H.264 480i/480p, 720p, and 1080i/1080p at 40Mb/second.

I had read about the Broadcom solution last December, but never had a chance to check it out until an Atom N270-based Advantech ARK-DS303 digital signage player arrived at the RuggedPCReview lab. It had the Broadcom module installed as an option, since signage player customers may have a need for high definition video playback.

To test the HD playback capabilities of the Broadcom Crystal HD decoder, I installed both QuickTime and the freeware Media Player Classic HomeCinema 1.3, copied a 250MB 720P high definition Quicktime (.mov) movie recorded on a Bonica HD video camera onto the Advantech player and then ran the movie side by side on an Apple iMac27 and a 22-inch display hooked up to the ARK-DS303, set to 1680 x 1050 pixel resolution. Amazingly, the DS303 kept up with the vastly more powerful iMac throughout the movie, with playback quality being almost identical. There was a very slight choppiness at times, but it did not materially impact playback.

I then ran a full 1080p MPEG4 movie trailer on the DS303 and it never missed a beat. In fact, it almost ran better than 720p video. That is very impressive for a low-power Atom player with just a gig of RAM and no fancy hardware. By comparison, an Acer Aspire One netbook with basically the same hardware as the DS303 sputtered along at just a few frames per second. Our findings are confirmed by this test of the Broadcom card by SilentPCReview.

On a personal level, what this means is that if you have a netbook that has an empty PCIe slot, you can get a Broadcom BC970012 board on eBay or from a company like Logic Supply (see Logic Supply BCM970012), download the drivers from Broadcom (see Crystal HD download page) and finally have decent HD video playback on your little underachiever.

For manufacturers and resellers of rugged tablets and other mobile devices based on the Atom platform, and especially the N270, N280 and the new N450 (and probably the D510 as well), by all means make the Broadcom board available at least as an option! Due to its low cost, the Broadcom BCM970012 PCIe board is virtually a no-brainer for N270/N280 systems, and the newer N450 systems can definitely benefit from Broadcom's follow-up BCM970015.

The video below shows the same 720p (1280 x 720) clip playing on an iMac27 on the left and on the Atom 270-powered Advantech ARK-DS303 with the Broadcom module on the right.

I should mention that the situation is somewhat different for devices based on "Silverthorne" Atom chips, i.e. those with Z5xx Atom processors. Those actually havehard ware support for H.264 and other HD decoding. However, in order to take advantage of that capability, OEMs must include the necessary codecs, or users must run applications that come with those codecs (such as CyberLink or PowerVideo). For example, a Atom Z530-based Fujitsu LifeBook UH900 currently in the RuggedPCReview.com lab easily plays 1080p video at full frame rates.

Fact is, at this point no one knows how the iPad will be received. Apple apparently felt comfortable enough with the tablet form factor to create the device and stake a good part of its reputation on it. Since the iPad is really a scaled-up iPhone rather than a pared-down MacBook, the question will be whether the iPhone experience indeed scales up to offer something the little iPhone just couldn't, or whether the larger form factor actually works against it as people may be more likely to compare it to a standard PC.

One thing is for sure: the iPad will put the tablet into the harsh light of public scrutiny again. This, of course, isn't new. The original IBM ThinkPad of the early 1990s was a tablet, and then, just as now, the tablet/pad concept was sold as something millions were already familiar with: Scribble on a notepad or relax in a comfy chair with a tablet computer that feels like a book or print magazine. The major difference between then and now, apart from almost two decades of technological advancement, is that back then handwriting recognition was seen as the key to unlocking the tablet's potential.

Unfortunately, handwriting recognition never quite worked out (though, with some training and given a chance, the software actually works very well), and current tablet efforts do not push recognition at all. Instead, the emphasis is on an attractive, elegant user interface with all the effortless swiping, pinching, bouncing and tapping that made the iPhone such a hit.

Will the iPad benefit industrial tablets by bringing more attention to the tablet form factor? It's quite possible, but there are some pitfalls. The obvious one is that the iPad will set a standard of user expectations (effortless multi-touch, elegant UI, etc.) that Windows-based tablets will probably have a hard time to meet. Another is that Apple's effortless, elegant user interface requires a flawless implementation of projected capacitive touch technology, something that may work much better on a small consumer device than a large vertical market device that users may want to operate with gloves on.

It's probably reasonable to assume that the iPad will raise expectations as to how tablets should operate. And raised expectations always mean that older technology will be viewed as lacking. So if users are driven to vertical market tablets just to find that they do not live up to expectations, the rejection and dissatisfaction will be more severe. Which means the overall impact of the iPad's publicity could be negative if vertical market tablets do not offer the same general improvements that the iPad brought to the consumer market.

What's the implication? For that we need to take a look at prevailing digitizer and touch technologies.

Almost since the very start of pen computing, Wacom's inductive technology has dominated the digitizer market with its precise, sleek pens that do not need a battery. The pen functionality of the Windows XP Tablet PC Edition, which was launched in 2002, was clearly designed for the Wacom pen, and the technology, for the most part, works very well. The primary problem with active pen solutions, though, is that you're dead in the water if you lose the pen, and despite tethering, spares, etc., it's just a matter of time until a pen gets lost.

Which is why resistive touch technology is being used as an alternative to inductive, and often in conjunction with it (so that the computer automatically switches from one to the either when according to certain rules). The problem with resistive touch is that it is not very precise, not well suited for inking and recognition, and very prone to misinterpretation. After all, the digitizer must figure out how much pressure represents a "touch" and also differentiate between an intended touch (like from a stylus) and an unintended one (like the pressure of the palm of your hand). Resistive touch doesn't work very well with Windows and its tiny check boxes and scrollers, though legions of Windows CE/Windows Mobile users have learned to live with it.

The respective shortcomings of inductive and resistive digitizer technologies led Apple to use projected capacitive touch, where a) it's either a touch or not a touch (no shades of gray depending on pressure), and b) multi-touch is possible. Combine that with Apple's interface magic and you have the elegant, effortless and seductive iPhone. Bingo, the perfect solution for tablets.

Or is it? Over the past year we've seen multi-touch functionality added to a lot of tablets and notebooks. I've tried several of them, and none worked very well. Those systems would have a few demo showcase functions, but capacitive touch and multi-touch really did not make the systems easier to use, and they were just another feature rather than the main mode of operation (which is what makes the iPhone such a hit). So simply "having multi-touch" is not enough. It may even work against a product.

This morning I came across a press release from Xplore Technologies, one of the earliest supporters and providers of vertical market tablet computers, where its president, Mark Holleran, lauds the launch of the iPhone as a great opportunity for the tablet form factor. Holleran points out the ease of use of tablets and views the launch of the iPad as a sign that "the tablet PC industry is poised for wider acceptance and accelerated growth."

I do think Holleran is on to something, but even if the iPad is a rousing success, it'll still be a challenge to translate the iPad/iPhone user experience into an equally satisfying solution for vertical market tablets.

Yesterday I saw an article entitled "Delays Decimate Microsoft's Enterprise Mobile Market Share" at channelinsider.com, and they asked, "So, what of the rugged device market? A market largely dominated by bulky devices running Windows Mobile from manufacturers like Motorola and Intermec. Howe (Director of Anywhere Consumer Research at Yankee Group) says that enterprise applications are becoming more and more prevalent on consumer-grade smart phones, and the rugged hardware manufacturers will become more and more niche-focused."

What they're saying is that enterprise and vertical market functionality is increasingly becoming available in inexpensive, standard consumer products, and the people who use that functionality do not want to walk around with two phones or handhelds. That's been pretty much accepted for a while now, as evidenced by the number of ruggedized handhelds that have integrated phones. The problem, though, as Howe puts it in the channelinsider.com article, is that "No one wants to go around looking like a UPS guy when they are out at the movies."

And perhaps an even bigger problem is that no one, including the UPS guy, wants to put up anymore with a clumsy, recalcitrant user interface that fights you every step along the way. Not when the iPhone and Android and Palm have shown us that it can be done so much better.

What will happen? I honestly don't think that Microsoft's mantra that handhelds need Windows CE because it leverages enterprise expertise washes anymore. Not when the handheld platform has been neglected to the degree Windows CE has been neglected. It's much more likely that Windows CE is still alive on vertical markets because it's a leap of faith to trust Apple or Google or open source to care about the relatively small vertical markets (even though some sales, like UPS, can be in the hundreds of thousands).

Yet, the fact is that I can now take an iPhone, which doesn't even have a scanner, and scan barcodes with its built-in camera. Or take pictures with it that are far better than anything I've seen out of the integrated cameras on Windows CE devices. And due to the laws of physics, small devices are often inherently more rugged (and easier to ruggedize) than large ones. Does that mean we'll soon see slightly modified smartphones do the job of rugged handhelds?

Probably not, but the thought definitely enters the mind.

The article really has nothing to do with rugged computing, but I think it's relevant here anyway because a) the fate of the Apple iPad will have a big impact on how tablets are viewed in the coming years, and b) because of the mobile industry's never-ending struggle to find form factors that are really right for a given job.

So here's what I contemplated:

This week I will order my iPad. Though I know it'll take a bit longer, I am aiming for the 3G model with 32GB of storage. When I get it, I will sign up for the unlimited data plan, forking over an even larger part of my disposable income to AT&T every month. What I do wonder is whether the iPad will replace my iPhone.

Silly question you may say. The iPad is not a phone, so how could it replace the iPhone? True, but I really don't consider my iPhone as primarily a phone. It is, in fact, a pretty crappy phone, with voice quality worse than virtually any cellphone I've ever had, going back to the original Motorola "brick." But I do need a phone for the few calls I make, and it doesn't make sense to carry a much more convenient little fliphone in addition to the iPhone, and so, yes, the iPhone is my phone, too. But if I checked the number of minutes I use my iPhone as a phone versus for everything else, everything else would account for about 95%, at least.

That's because the iPhone has pretty much become my information and entertainment device of choice. Before I leave the house I check the weather and temperature on the iPhone so I know what to wear. I get my news from the iPhone's USA Today and CNN apps (and even a couple of local and foreign newspapers), and more detailed news from the NY Times on the iPhone. I keep in touch with my Facebook friends on my iPhone. I read e-books on it. I play games on it. I use it when I go running and want to keep track of my time. I use it to check prices and read reviews while shopping. I check sports scores, the load on my servers, new messages on websites I post on. I do all that on my iPhone because it's so darn handy and convenient, and because it is good enough to do all those things. Had anyone told me a few years ago that, yes, it WILL be possible to use the web on a tiny device not as just a technology demonstration, but because it really works, I probably would not have believed it. After all, everyone had tried and it just didn't work. Until the iPhone.

So now the iPad will do everything the iPhone can, but on a much bigger screen. No more squinting, no more screen rotating to make columns more easily readable, no more constant pinching to zoom in and out. That will all be a thing of the past as what we have all been waiting for is now here with the iPad, the book/magazine reading experience in an electronic device. Because that is the one remaining hang-up that keeps print newspapers and mags in business; they are more convenient than reading on a laptop computer.

But now I wonder if the iPad will do everything the iPhone can, and do it better. Will I appreciate the much larger screen, or will it simply make the iPhone experience big and unwieldy? Will I have much higher expectations from a "real" computer like the iPad than I have of the little iPhone? For example, will I still tolerate the lack of Flash on the iPad? Will iPhone apps still look so terrific and clever on a much bigger screen, or will I expect real computer functionality? Will I start whining about the lack of "real" software? But most importantly, will I be able to use the iPad like I use the iPhone, just whipping it out wherever I am? Because if not, it may not work, and the new big iPhone will be something else that'll have to fly, or fail, on its own merits.

I won't go into the long and checkered history of Windows CE here, nor into Microsoft's bewildering meandering with nomenclature or the disruptive inconsistency and frequent course changes. It all has become an almost impenetrable mess even for longtime followers of Microsoft's smallest OS. Unfortunately, Windows Phone 7, Microsoft's latest knee jerk reaction to a changing smartphone market that has essentially relegated Windows Mobile into insignificance, casts more doubt and shadows on Windows Mobile than ever.

While in the real world, the one where manufacturers make and sell rugged mobile products, we continue to see Windows CE 5.0/6.0 and Windows Mobile 6 and 6.1, in the hype and announcement world, Microsoft has announced Windows Phone 7 OS, a trendy me-too music player interface trying to leverage the floundering Zune music player platform while copying iPhone and social networking concepts. It's hard to see how Windows Phone 7 could make a dent into the smartphone market, and it is most certainly not the future in commercial and vertical markets.

So where does that leave vertical markets who probably aren't thrilled at the prospect of being stuck with an increasingly obsolete Microsoft mini OS? Not in a very good position. Let's face it, the odd Windows Mobile 6.5 interface is essentially unsuitable for vertical markets. And now that Microsoft, scrambling to remain relevant in the mobile market, is putting its eggs into the projected capacitive (multi) touch basket, it's hard to see how any of the older versions of Windows CE/Windows Mobile (which is now renamed to "Windows Mobile Classic") may benefit from the Windows Phone 7 OS. Yet, something with "7" in it must happen to at least give the impression that Windows Mobile is moving forward (and to benefit from the relative shine of Windows 7).

So we have a situation where only last year, Microsoft's entertainment and devices division president Robbie Bach waxed enthusiastically about WinMo 6.5 ("It will give you access to more websites than you will be able to get to on an iPhone that will work actively and work well. It really is a much better experience.") and now the future of 6.5 already seems quite uncertain.

Personally, I think what may happen is that Microsoft will quietly integrate Windows CE/Mobile into its Windows Embedded Products business. That area already includes Windows Embedded CE in addition to Windows Embedded Standard, Windows Embedded Enterprise, Windows Embedded POSReady, Windows Embedded Server, Windows Embedded NavReady, and so on. The stated purpose of Windows Embedded CE is to "develop small footprint devices with a componentized, real-time operating system. Used in a wide array of devices, including portable navigation and communications devices." That makes sense.

One problem with this approach is that one part of the appeal of Windows CE/Windows Mobile was always that people were already familiar with its look and feel. Today, that look and feel is ancient, just as are the very visible underpinnings of Windows CE that essentially date back to the last millennium. And with Windows Mobile Pocket PCs gone and Windows Mobile phones irrelevant, that part of the leverage is gone as well. A new interface approach is sorely needed, but if Windows Mobile 6.5 and Windows Phone 7 are any indication, Microsoft's thrust is in the Zune player and social networking arena.

So what will the small but significant number of vendors who make and sell Windows Mobile devices do as their chosen operating system platform looks increasingly dated and is becoming a target of customer dissatisfaction? That's a good question. You can never count Microsoft out, but after all the fumbling with their mobile OS over the years, hopes for a cohesive, logical and compelling direction for Windows Mobile seem optimistic.

The new Intel Core i3, Core i5 and Core i7 processors come in numerous versions with two or four cores, clock speeds ranging from 1.06 to 3.33 GHz, maximum power dissipation of 18 to 95 watts, different process technologies, different degrees of integration and different complementing chipsets.

Unfortunately, while the difference between Intel's older Core 2 Solo and Core 2 Duo processors was pretty obvious, differentiating between the Core i3, Core i5 and Core i7 chips can quite confusing. As a rule of thumb, the 3/5/7 sort of represent Intel's "good," "better," and "best" processor solutions in any given category just like BMW makes 3, 5, and 7 series cars (though the analogy only loosely applies). Core i3 processors, for example, do not have the Intel TurboBoost feature that provides extra performance via automatic overclocking and seems more than just a marketing feature. Core i7 processors generally have more cache and support more of the special Intel features and technologies than Core i5 and Core i3 processors. There is, however, more than a bit of overlap in functionality and performance, and figuring out which one is best suited for a task won't be simple.

As of February 2010, Intel has announced about three dozen of the new Core i3/i5/i7 processors. About a third of them are designated as embedded processors, which makes them especially interesting for for embedded systems designers due to considerations such as package size, structural integrity, error correcting code memory, system uptime as well as, and perhaps most importantly, an 7-year extended life cycle.

Intel has always had an excessive fondness of code names, and it's no different with the new Core processors. It's therefore useful to know that Intel distinguishes between generally desktop-oriented "Piketon" platforms that use either two core 32nm "Clarkdale" processors or four core 45nm "Lynnfield" processors (and usually have TDPs that makes them unsuitable for most mobile applications), and mobile "Calpella" platforms that use two core 32nm "Arrandale" processors with lower thermal design powers (generally 18 to 35 watts).

So let's take a quick look at Calpella and Piketon.

In essence, "Calpella" is Intel's new "low power" platform, though there is now a much sharper differentiation between the really low power Atoms and the low power but rather high performance new Core processors. The Calpella class "Arrandale" CPUs are based on the latest 32nm lithography. They are are essentially the successors of the mobile Core 2 Duo CPUs and come in standard, low voltage, and ultra low voltage versions at various processor clock speeds.

There are, however, some interesting differences: As a first in this class of Intel CPUs, the memory controller and reasonably powerful integrated graphics with HD hardware acceleration and other new capabilities are now part of the processor, which means no more conventional Front Side Bus and "Northbridge" part of the chipset complementing the processor. These integrated graphics can be turned off when they are not needed, and Nvidia (who is probably not that thrilled about this Intel move) has already announced their "Optimus" technology (see what it is) that automatically determines whether to use the integrated graphics and extend battery life, or use an external NVIDIA GPU to boost graphics.

Like the Core 2 Duos, "Arrandale" processors have two cores but the new chips use Intel's HyperThreading technology that act like virtual cores, making the operating system think it is dealing with four cores. The new chips also add L3 cache while the Core 2 Duo chips only had L1 and L2 cache. They require DDR3 RAM that supports higher speeds (up to 1,333MHz). An interesting new technology is Intel "TurboBoost" that automatically steps up processor core speed if it detects that the CPU is operating below certain power, current, and temperature limits.

The new embedded Intel Core i5/i7 processors range from ultra low voltage models with a base clock frequency of 1.06GHz and a Thermal Design Power of 18 watts to low voltage models with base clock frequency up to 2.0 GHz and TDPs of 25 watts, and standard voltage models with base clock frequencies as high as 2.66GHz and 35 watt DTP. This means they're suitable primarily for higher end, high performance rugged notebooks and tablets, but not for lower end systems that require the still significantly lower power draw of Atom-based prcessor technology (or emerging alternate solutions such as the Nvidia Tegra).

"Piketon"-class processors also include a variety of Intel's new Core i3, Core i5, and Core i7 CPUs but unlike the "Arrandale" versions they are mostly standard voltage, higher-powered chips that include both older 45nm technology "Lynnfield" versions of the chips (four cores but no integrated graphics) as well as newer 32nm "Clarkdale" versions with two cores and integrated graphics. These are performance-oriented processors with TDP ratings of 73 to 95 watts and thus unsuitable for most mobile applications.

What about performance? We haven't had a chance at benchmarking any rugged systems with the new processors yet. Intel and other benchmarks of all new Core processors suggest a hefty 30-60% performance increase over equivalent Core 2 Duo processors at roughly the same TDP levels. Literature and previews also suggest that the performance of the integrated graphics processor is improved by perhaps about 50% over that of the predecessor GM45 platform. There is also said to be better 3D performance, high definition video hardware acceleration, audio and other advancements.

It should be interesting to see who is first in making the new i5/i7 chips available and how they'll work out in rugged systems.

For a comparison table of all Intel Core i3/i5/i7 released through January 2010, see here.

Fujitsu, of course, has been into tablets longer than most and probably has the most experience of any Tablet PC and convertible vendors. Fujitsu had the PoquetPAD and 325Point tablets a decade before IBM reinvented the Tablet PC in 2002, and the company is now in something like the 40th generation of tablet technology. Yes, the 40th. During the 1990s, Fujitsu built a successful business around vertical market slate computers, most notably the Point and Stylistic models, with the latter line carrying on to this day. For a while Fujitsu also offered Windows CE-based devices such as the PenCentra line. Fujitsu also offered small business-oriented notebooks with pens when almost no one else did. What it all boils down to is that there's no one who has more corporate DNA in tablet and slate computers in any number of form factors.

Paul pointed out that at this point, Fujitsu is the only company that offers both slate AND convertible computers. There are many that have a notebook convertible in their lineups, such as Dell and HP, and there are some that only offer tablets, such as Motion Computing, but no one offers both in their market (one could argue that DRS ARMOR and a couple others do offer both platforms, but those are in the heavily rugged markets).

Anyway, it was interesting to hear Paul tell that Fujitsu is seeing a heavy migration from tablet to convertible. Customers are transitioning from the Stylistics to the more conventional Lifebook convertible notebooks that can also be used as slates by rotating the display and laying it down flat on top of the keyboard. That probably explains why Fujitsu is now down to one single model in the Stylistic line, the Stylistic ST6012, whereas the company offers no fewer than six different convertibles (the Lifebook T1010, T1630, T2020, T4310, T4410, and T5010).

With Panasonic making a big issue out of their rugged computers still being made in Japan, I asked Paul if the Fujitsu tablets and convertibles are also still made in Japan. The answer was yes, all Lifebook tablets are made in Japan, and all E-Series machines as well. However, while with Panasonic it was pretty clear that they made a connection of made in Japan = much lower failure rates, Fujitsu makes no such claim. Paul said failure rate stats are compiled, but given the vast differences in markets served makes any meaningful comparison essentially impossible.

I asked Paul why Fujitsu does not market its computers as "business-rugged," "semi-rugged," or one of the other ruggedness categories. The unequivocal answer: We don't have rugged tablets. Ours are durable, well-built, according to the markets we serve. We don't lose many customers because of ruggedness requirements. Fair enough. Full or even partial ruggedness can add a lot of cost and weight, so if it is not needed, why add it. Paul points out useful features that prolong the life of a computer, like a user-cleanable dust filter, accelerometer-based hard disk protection, a display hinge that rotates in both directions so it won't get damaged by inadvertently turning it the wrong direction, and so on.

With reference to the rotating display hinge, I asked Paul whether he knew why all Tablet PCs since 2001 have been designed with the same exact rotating hinge that lets users rotate the display and then fold it flat on top of the keyboard, LCD facing up. This is a good solution, but in notebook mode, the display flexes when you tap it with the pen. In the 1990s there had been several alternate solutions that minimized or eliminated the flex problem, but they are all gone. Paul said he wasn't aware of any patent protection or other reason why designers should be limited to the rotating displays, but it's a solution that works, flexing is not an issue when the device is used in tablet mode, and with the increasing importance of touch, flexing again is not an issue. Cost, too, might be an issue in staying with standardized solutions.

We also discussed the inherent suitability of a full desktop operating system for tablet and touch use. In my opinion, Windows itself has always been a major factor standing in the way of widespread tablet adoption; it's simply not suitable for pen operation. Paul felt that Windows 7 has made great strides towards better usability, but that in vertical markets it's really all about custom applications anyway, and those are usually optimized for whatever input medium is used.

With the recent advent of Intel's new Piketon and Calpella processor/chipset platforms I asked Paul what Fujitsu's plans were for the Intel Core i3/i5/i7 processors. His answer was that, for the most part, they prefer to use standard voltage processors that generally cost less, offer better performance, and represent an overall better value for users. Based on the benchmark result of our review unit that's equipped with a 2.53GHz Core 2 Duo P8700 with a thermal design power of 25 watts, we see no immediate reason for a chip upgrade: the T4410 scored the highest overall performance results of any Tablet PC we have ever tested, and it still had an idle power draw of just 9.9 watts, barely more than most Atom-based systems.
