Also, in regards to Windows 8, so far as I remember, Microsoft is only supporting Cortex A9 based ARM processors that are 1+ GHz for performance reasons. Real information is pretty scarce about Windows 8, but the ARM PC at Computex was running on a Tegra 2, which is a dual core 1 GHz proc that is Cortex A9 based.
So if that's true, Win8 isn't possible.
