Guys, it's been 6 months since the launch of the tbMBPs. Have all the issues been ironed out by now, or should I wait another 6 months? The problem is that I don't have an easy way of returning a mac once I purchased it, and my 2012 rmbp is on its last legs.
I purchased a 13" tbmbp in early november, but returned it after 3 days due to the persistent graphical glitches during startup and restarting (i found that a consistent way of reproducing them is downloading the recovery partition, and rebooting into it).
I'd wait. Supposedly the update fixed the graphical glitches, but it didn't do anything for the 15" tbMBP I purchased a few days ago. Currently I have to unplug from my display to do any real work as I get a complete graphical meltdown when connected to my thunderbolt display. This is the main problem I have amongst other many other little bugs and glitches between hardware and software.
There are others who are perfectly happy and well adjusted to the tbMBP. What is striking to me is I constantly read things like: "It took sending back the tbMBP 1-5x but I finally got one that works and I'm super happy!" I know this isn't the norm, but I can't take that risk as I need this thing to run flawlessly for work and can't have any downtime.
I'd wait until the next version, let apple iron out the kinks. I think what I'll do is purchase a 2015 right now and reevaluate next year once the updated ones come out and there is more feedback.
