Microsoft's WP7 is not Windows 8. They are 2 different OS's, so they'd have to use both, on the phone's hardware. So far I haven't seen anything more powerful than a single core WP7 phone. Plus, are you asking for an Atom-based phone? However, I do think docking a phone into different screens has potential. I was thinking before how Google could do like 3 "UI add-ons" for the core Android code. So you get your phone UI add-on by default on the phone itself, then when you dock it to a PC screen, you see the Honeycomb UI, and when you dock it to a TV, you see the Google TV UI. I think different types of devices and form factors mandate a different UI. You can't really shoe-horn a UI from a 3" screen to a 50" screen. But of course, they could still be made so you transition painlessly from one to the other, and have the same design style. But they should all be optimized for the form factor, device type and screen size.
