A version of that >operating system that is optimized for Xscale may not be available until 2004." The PXA250 might have special power-saving logic that's controlled by the operating system, so the PocketPC OS might need new code to get power consumption down to the advertised levels (i.e., as low as a 206MHz SA). But just because the PocketPC OS might not be power-consumption friendly doesn't mean it forces the chip to run at 200MHz, which is apparently the conclusion the article is drawing. That's sort of like buying a 2GHz Pentium but only being able to run it at 1GHz when you're using Linux. Things just don't work that way. -Tom
