overyone's comment has just highlighted a problem with the design of the Iyonix. it's a bit like the A3010 in that it cannot be given a simple upgrade you are stuck with a 600Mhz computer the only way to make it go faster is to go cap in hand to intel for a faster chip, the problem with this is that there are no faster chip in the Intel roadmap.
which make the Iyonix a deadend with little or no upgrade protental.
So what will it be next move on to the next Xscale referance design, maybe the next one will be based on a faster Arm Design. but then this one has already been designed by another company. This after all what made the Risc PC design so longlasting upgradablity.
