I have a Nokia Lumia 920 and other than battery life I am extremely happy with it. WP8 might prove to be a nice middle ground between iOS and Android. If only more people would give it a chance, it's a really stellar experience.
I actually switched to iPhone 5 after a couple months of Lumia 920 usage. Bought it right after release, with the wireless charger and stuff. I really liked the device.
My problem was the fucked up regional annoyances. If you are not in USA, good luck! No full size skydrive photo uploads for you! No Xbox online.. No album covers in music app. A lot of missing apps in store. No this, no that. Well, I have no such problems with iPhone and Android.
BTW: After I switched, I sold my Lumia to a friend and used factory reset before handing the phone. Guess what? There is a known bug in factory reset that bricks the phone and it was apparently not fixed in 2 firmware upgrades that I got during that time :)
Are you in China? Yes, the regional annoyances on the 920 suck. Ironically, they are only an issue on the Nokia phones; the HTC phones (like the HD8) allow you to change to the American app store very easily.
iPhone 5 has a few that are not obvious, even if it does allow me to easily switch to the American app store. Chinese versions of Android are a complete pain, but the devices are easily rooted.
At least it is only software-regional. I've bought the One X in Taiwan when it was brand-new and now I have an Android 4.0 phone that only supports the following languages: Chinese, Simplified Chinese and English (I'm still too scared of Buyer's Remorse to check what else is different).
...that was a pretty cryptic post, what I meant is that it only supports these three languages no matter where I am (different hardware/OS per country). It's like buying a movie on a vacation and then finding out about DVD regions.
