The TB is too buggy. The reboot issue is not fromt he last update, it is a flaw in the OS itself and plagues most Android phones, not just the TB.
Also, unless you want to disable 4G, don't expect your battery to last till lunch time without jumping through hoops and disabling everything.
The phone wasn't ready for prime time and still isn't what I would consider a finished product. It's beta at best.
If 50% of the people aren't having the problem it's either (a) you have a hardware issue, (b) you insist on keeping your other apps in the phone and don't want to troubleshoot and one of those can be the problem, (c) You don't want to do the dreaded factory reset to really see if it's the phone or just one badly written critical byte.
I have my own beefs - like VZW laying a major egg telling the tale of extensive testing, etc. for us to find out that there is no internal memory that is truly user accessible (not 8GB) and that the battery will not last a full day with 4G (only the extended battery or some other higher capacity battery is the cure.) But other than that and the annoyances (2 color LED, stupid placement of the micro usb, no video recording on internal memory) the phone works darn well and very speedy indeed. The reboot issue? Haven't had it happen except on occasion. I have other problems that crop up and I know I have to find out why (e.g. getting sudden major power drain and can't figure out why... defective phone? I think not.)
