If you're an android user, I'm sure there will be a launcher for it soon enough anyway. Try launcher 7, the interface is absolutely crazy.
Launcher7 is what woke me up to Windows Phone when I had a Droid. I switched launchers like underwear before I discovered L7, and stuck with that for the remaining six months I owned the phone. So much better than the stock Android launcher and so much different than any of the other launchers out there.
Also, I really hate the interface. It's really childish and simplistic looking, like I'm not using a phone but rather some kind of electronic mall kiosk menu. If they can actually deliver an interface that doesn't make me feel like I'm being sold some flashy crap like a futuristic display from Minority Report, I'll consider a Windows Phone.
IMO, it's beautiful in a simplistic/minimalistic kind of way. And it is by far the easiest interface to use of the three major players... at least for me. Get in, get out, get on with my life. Exactly what I want from my device.
WP7 is good, and is a match for Android and iOS. But MS were too late with it. In any case, the fact that you're more or less screwed if you bought a WP7 phone, really makes me ignore WP altogether.
It puzzles me : is a phone that runs WP7 not powerful enough to handle WP8 ?
A lot of the WP8 issue is hardware, from what I understand. Display, scaling, NFC, etc. That said, Windows shot themselves in the foot by proclaiming that all WP7 devices couldn't be updated to WP8. The average consumer wouldn't know the difference between WP8 and WP8.01, the latter of which could be the Windows 7.8 (stripped down WP8) they plan to release to all legacy phones.
