Why is no one using the Marvell speedy and powerful PXA320?

When we reviewed the TDS/Trimble Nomad last year here at, I marveled over the machine and noted, "The 800 MHz Marvell PXA320 processor certainly had something to do with it. The difference between it and the 624MHz PXA270 is much larger than we expected."

In fact, the chip performed so well in the Nomad that I was certain other manufacturers would quickly follow suit and use the formidable PXA320 chip as well. Interestingly, that didn't happen. If I remember correctly, the only other product I've come across that uses the PXA320 is the Aceeca Meazura MEZ2000, which I think is still in the planning stage. Everyone else still seems to be using the older PXA27x, even in new designs. The PXA27x is certainly a good and time-proven processor, but it is no match for the PXA320 when it comes to performance.

Maybe something is going on that I am not aware of. Maybe Marvell isn't pushing the chip and it's such a secret that no one realizes technology has advanced. Maybe it's too expensive, or has some drawbacks I am not aware of. As is, the Nomad with its powerhouse PXA320 chip appears to continue to enjoy a significant performance edge over anyone else out there.
