Here's a comment on the first Windows Tablet running Win 8.
Now that has a VERY powerful processor in (probably 30x-40x faster than the one in the raspi). I think it highly unlikely that Windows 8 will run at an acceptable speed, if at all, on a Raspi.
Yes it does but that's an x86 (x64, I believe) processor, not ARM. They were demoing the ARM version, but have not yet released it to anyone as they don't think it's quite ready yet.
I am interested in whether it can be done or not, but my interest is from a purely nerdy point of view. For the mainstream RasPi, a slimline Linux distro is the way to go - no question. I would be interested in running Win8 (if at all possible) on a RasPi, but that's because I like tinkering and using things in an unconventional way - such as running OS X on a regular PC (moral/legal questions aside), or playing with BeOS/Haiku, BSD, etc. I'm looking forward to the first previews of the ARM version, as I'm really interested in giving it a whirl on my tablet (which, with it's dual-core Tegra 2, should have more than enough grunt).
For what it's worth, apps for Win8 ARM should not be a problem. It's unclear whether Win8 ARM will be backwards compatible with existing x86 software, but I seriously doubt that will happen; even if it does happen, the RasPi hasn't got a hope in hell of running that kind of compatibility layer - the processor just does not have the grunt. However, Microsoft have advised that any app written for the new 'Metro' framework (the fancy "tiles" thing) will work on both x86 and ARM with no cross-compiling or separate versions needed. What that means in terms of ARM hardware requirements is yet to be revealed. I doubt you'll see full versions of heavyweights such as Office or Outlook on ARM though - that just doesn't strike me as the target market for the Windows 8 ARM platform.
EDIT: PS, MS have also confirmed that the only way you'll get apps on to Win 8 ARM will be through the new app store they're creating. In that regard, it'll probably be much more like the locked-down walled-garden of the iPad than the developer/hacker/nerd-friendly Android.
