I had a spat of batteries blowing up on me before this one otherwise I may even still be on an 8 or something lol. I'm not even using 1/3 of my storage space. All my apps run more than fast enough. There are no new features I feel I'm missing. I think the first thing that'll move me off is improvements in the camera. Even compared to the 13 I could tell how much better the camera is in low light conditions.
