I dunno... With a cellphone, ARM makes sense. With a tablet, though, I'd want an Atom, so I could run fullblown applications(including legacy games via Wine). And still have decent battery life. On top of that, I don't know how you'd run Windows(of any sort) on an ARM proc anyway - It'd lag horribly. Even un-optimized Linux is slow. With a hefty Atom, you might get it running acceptably.
