Re: the nokia purchase...
Windows phones I had (many review luminas) were dogs, poor camera, flaky Bluetooth, windows phone was a battery hog, lucky to get 3/4 of a day whilst my android phone was still going strong, windows phone OS was also really buggy, Bluetooth stack in particular, but they all regularly rebooted randomly, often mid call.
The dismal app selection just sealed the deal, but the problems were more then just apps
