It's strange how hit and miss all of these issues seem to be. I ordered mine fairly early on, had it for weeks, and haven't had a single problem yet (with the tablet or dock) other than a complete lack of gps capabilities (which I don't care for anyway, it's useless to me). No random reboots, no screen issues, wifi has been fantastic (as good as my phone without fault), etc.
It's disappointing hearing all the reports of people having problems, it's a fantastic tablet and could have had an amazing impact, but seems to be it's own worst enemy.
I will note I haven't been having problems with any of the updates (other than losing root, but I got it back) and I did experience a youtube issue, but before I installed the update. So definitely on youtube's end.
