I ordered for my wife a 13" Haswell rMBP, and it arrived near the end of Februrary. A little over a week ago, the sound stopped working (the system could no longer see the Internal Speaker, and headphones didn't work either). I took it to the Genius Bar and was told that they'd try replacing the speaker, but that ultimately it was probably a logic board issue, which ended up being the case. Since it's still well within the warranty period, they ordered the part and performed the repair for free. My question: How common is it for an rMBP logic board to die after 3 months? Does this mean my wife got a dud? I previously owned a 2011 15" MBP (non-Retina, obviously) for almost 3 years and never had a single problem with it. I sold it and bought a 15" Haswell rMBP shortly after they were released in October. I didn't buy AppleCare for either rMBP because I had such a positive experience with my previous MBP (which was also my first Mac).
