I bought one a year ago. It's adequate for my purposes (alarm clock, phone, Midas M32 controller, notes, TuneIn, general WiFi access, security DVR monitor, secure password storage, and a couple other things). I put it in an Otter case; I've dropped it a couple times with no breakage. Battery life is good, but WiFi drains it faster (to be expected). Occasionally use cell data. Voice quality is generally decent. Haven't had any problems with it: no reboots or crashes. Most of the day, it sits on the counter idling away.
YMMV.
