Not sure if anyone's posted this but Microsoft is offering Lumia's (flagships) a buy back of 150.00 for these phones. Not a bad deal considering they sell the 950 for $550.00. That's like getting the 950 for 400 smackers.
I never owned a 920, so can't directly compare the two, but I have been very pleased with my 950 on .164 and .218.....love the camera, and the display is beautiful. Battery easily gets me through the day with moderate use.
It is still a little buggy at times, but nothing serious as far as I'm concerned, I know it has been "dinged" a bit for not feeling "premium", but it feels good in the hand to me, and I put a case on my phone anyway so it doesn't really matter. It replaced a GN3, and the 950 feels much higher quality to me, and performance is way better. I would definitely buy it again at this point.
