The app issue is becoming less a problem, the store has exploded over the last year. There are couple of missing apps but I've found alternatives.
The annoying part is some local mainstream stores ignoring WP and not making apps and having to hope that a 3rd party will make one.
The Lumia phones are some of the best built phones I've used, no lag or slow down. Even the 8MP camera on some models can take some amazing photos.
Will be upgrading when the next wave come through, I dont miss having to charge everyday :-)
I wanted to try something new so last time I bought I phone I got the Lumia 1020 and the camera is really something else compared to other smart phones, specs of it:
41 MP (38 MP effective, 7152 x 5368 pixels), Carl Zeiss optics, optical image stabilization, auto/manual focus, Xenon & LED flash
The lens is quite larger then most phones so much better in low light environments so it takes great pictures for when I do not have my camera with me. Really like the phone, it has some WP quirks I do not like but overall it's great, responsive and solid as a brick and with a great camera on top of that.
