Check out Windows 8 on a $68 VIA 8850 Powered 7" capacitive tablet! (just a home replacement) What is the difference in performance and potential features between an optimized Android Home Replacement and a "real" native Windows RT machine?

I think it is obviously meaningless for Microsoft to insist on making Windows 8 a separate closed/proprietary/incompatible ecosystem to Android. And it'd be even more wrong if Microsoft wants to forbid tablet and laptop makers to dual-boot Android with Windows RT.
