Well my 6 was waiting for me when I got home. First impressions:
- the gray is really nice. "Space gray" is a good description.
- overall look and form factor is A+ as expected
- in the pants pocket it actually feels better than the 5. The thinness is more important here than the length and width.
- it feels bigger in the hand. For two-hand use (my normal mode) no problem, but one-hand use will require adjustment. My hands are average to slightly smaller than average.
That's all I got, haven't even fired it up yet. :P As I don't have a case for it yet I don't want to take it golfing tomorrow, so I'll set it up in the afternoon.
