Decisions..
A neighbour of ours got one of the new Luminas recently (925 I think) and absolutely loves it. She's your "joe public" type of user, not a geek, but being in her mid-30s technology literate. She's used iOS, a variety of Android phones, and says this is her favourite so far.
After using it myself for a bit, I have to say I do like the Windows 8 mobile OS a lot. It's clean, quick, stylish, and if I wasn't holding out for the iPhone 5S to replace my knackered iPhone 4, then the Lumina would probably be the phone I'd get.
I can't be arsed to spend hours tinkering around with configuration on a phone, I have desktop machines to do that with, and although I own an Android device I've never really found the OS my cup of tea or "fun" to use.
