If you were to believe the moaning on this site, then about half the rMBP are faulty, which is of course absolute bollocks. When Apple said it's the best portable they have ever made, they were telling the truth. It's an amazing computer, so thin and light compared to the previous 15". The screen (no matter which manufacturer) is truly a thing of beauty and a real game changer once again from apple. The speakers sound superb for a laptop, the graphics are great (even if you want to game). Battery life under ML is amazing, I'm getting an average of 7.5hrs with screen at 80% brightness. So just remember, for every moaning thread about having swapped out their rMBP 7 times or whatever, there are hundreds of perfectly happy users of this brilliant piece of technology that don't feel the need to let everyone know how perfect it is.
