Long-term lurker here, sorry if this was answered somewhere else. I just ponied up for my new 15'' rMBP (late 2013), and want to know what should I check for in the next two weeks before my return window runs out. Didn't get AppleCare yet (I'm waiting). I know there was a bunch of hubbub about the rMBP displays (LG vs Samsung) for example. Please experts, tell me what I should check for to make sure everything is in order. So, what now?
