Switched from an iPhone 6 to a Nexus 6P in January. Couldn't be happier! Sure it isn't perfect but no phone is and the 6P, for me, gets closest to the perfection goal than any other phone currently available.
Also the camera in the 6P is excellent which is a lovely surprise for a Nexus! It holds up well, better in some situations, to the brand new S7 Edge camera in my experience (my father has the S7 Edge so this was actual personal experience).
Yes I am looking forward to the camera especially and the quality and size of the screen for my aging eyes. @bithust do you use hands free phone dialing from a car? If so what car model and how is your experience with HFD?
