Another 1 of the 4
Count me in. I've got a 1020 which has been freezing and rebooting since I installed the developer preview (of 8.1, I think) sometime in the middle of last year. It locks up most days, and reasonably frequently more than once in a day. I originally let it slide as part of the whole "developer preview" thing, but neither the official RTM Cyan update or the more recent DP updates have helped. At least it's slightly less annoying now that WP can finally automatically re-set the correct time after a hard reset.
What's really annoying is that the only time that anyone from Microsoft had posted any information to that thread is after someone got Brian Harry (from the Visual Studio Online team) to chase it up by posting a comment on his blog, back in November. They pinged Brian again recently, and apparently he raised it with executives in the phone division and STILL no-one from the phone division has given us an update!
Also: They apparently responded to El Reg about this article, but again haven't felt that maybe they should post on the thread in their own forums.
I guess Apple and Google can be just as bad, but it's extremely distressing to be actively ignored.
