I've dropped it and had it slip out of my hands over 10 times in the span of a month, luckily i'm trading it in when i upgrade and physical damage (of the casing) doesn't matterI hear you. In the past I always sold my iPhone just week or so before. And it used to be within a few hundred dollars of the new phone's cost. With these phones hitting $1500-2000 it's going to be challenging to keep doing that.
I know though once they're in stores, I'm going to have a hard time resisting that larger OLED screen.
And yeah - I had that exact response the other day when using my wife's 7 Plus! Couldn't believe how slippery it felt compared to a glass back.
