Windows 8 ARM: Will its Launch be as Lame as Honeycomb and Windows Phone 7?
Intel, speaking out of turn and damaging its intimate relationship with Microsoft, has revealed that legacy x86-compiled software will not work on the ARM version of Windows 8. In all likelihood, this means that Windows 8 ARM machines — tablets and smartphones — will ship with a very small library of compatible apps.
Windows 8 ARM will be the first full-bodied version of Windows that has been completely severed from its x86 ancestors. No Windows software will work on the ARM version without significant code rewrites and recompilation.
