OK, a week out & I'm finding some faults that aren't big; considering the cost.
(1) The wifi range is low (2) the camera is only fair. It'll capture a shot; but not quite in the league with my old 3GS (3) alert seems tied to all volumes together incl ring volume (4) for some reason in calendar I can't always add to an event; like the capacity is full (5) processor is slow! can be a short wait ...
I'll add that cell call quality is perhaps the best I've experienced.
$40.99 on AT&T online as a prepay phone Z992
The wifi works fine < 75 feet for me, the camera snaps 16x12 pics (which is bigger than you're ever going to view on a modern display, shy of a dell 30inch, anyway (edit: I'm basing this on a standard 1920x1080 display in which the image will have to be scaled down to fit vertically)), the volume thing is annoying though.
As for the calendar, I haven't bothered with it.. The CPU is actually fast if you compare it to other similarly-priced phones.
It is marketed as an entry-level android, and for the price, I don't really think you can beat it.
My only major complaints thusfar are:
