I don't know anyone with a Windows Phone, but maybe I shouldn't expect to at the moment, because WP (8 at least) is so new. Most folk I know are on contract and midway through, so they're not going to change for a time. I know quite a few teenage girls who are quite happy to have some old rubbish phone and are quite happy to upgrade to some slightly less old rubbish phone because that what their mates do, and they don't do OSs anyway. I know old die hard iOS and Android fanboys who will never change. However, I'll say this, when I've shown my 820 to non WP users, without exception, the reaction has been "Wow", with perhaps the caveat that a few have commented that "It looks very complicated". Make of that what you will.
