Honestly... no complaints. Quite happy with it. I've had several long travel days without Wifi, or long days in general (wedding last week, up from 730am to 3am), and the battery always holds up superbly well.
Build quality has been good for me, screen quite good (though sure a little hard to see in bright glaring light), and I think the camera is fine. I'm not expecting to take a Pulitzer prize photo with my cell phone.
Phone has remained super snappy with performance, and I think over the months may have had ONE random reboot and that's it.
So yeah, no complaints. Happiest I've been with a phone in as long as I can remember.
