Today, I noticed a vertical line going down the right side of my MBA purchased in June (Haswell). I've tried everything from resetting the PRAM to reinstalling ML, with no success. Sigh. Do you guys know roughly how long it takes for Apple to repair a machine with an issue like this? I'm so bummed, and I can't really afford to be without a computer for too long. It's very noticeable and clearly a hardware defect.
