1) Somebody already told you this, only iDevices hold the value, everything else would value peanuts after a couple of months. 2) This happens with Apple too. 3) I don't have that problem, did you check that? Maybe is a problem in your end. 4) My 1 years old LG android 2.3 got stuck with that version for good. On the other hand, WP8 doesn't even have a year.

I had been used 4 platform (ios, android, BB and WP7 & 8) And my Lumia 920 is my all time favorite smartphone and it is a pleasure to develop for it in comparison with Android and iOS. So I guess is a matter of taste
