Few more physical things about the phone before I can move into talking about the internals.
The power button on the right hand side is conveniently placed just a bit over halfway through the side. This makes it much easier to reach for it than having it on top. There is a slider to silence the phone in the traditional power button place in this phone. A feature that surely is useful, but I still prefer the control of profiles based on whether I'm wearing my watch or not.
