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 :)
