3D Touch, interesting for a 6S+ unless you have two hands. It will be a useful feature in the bottom half and right side of the display but its going to be hard to use on the left and top. I can reach all of my 6+ now but I don't think I can force touch at the edges away from my right hand one handed. Maybe if I went with the 6S model instead. I just don't know at the moment. I was reading rumors of a higher resolution display and it didn't make it. I will have to think about this one a little.
