I've had a rMBP for the past two months. When I first received it, I didn't notice any dead pixels. Now it seems that a black pixel is visible on a white screen. It's the only one I've seen so far, but it is a problem for me. Apple's quality control is abysmal, and customer service is no help. I could try to have the screen replaced, but the Apple rep said they won't do it for one dead pixel. That's preposterous! Apple charges a lot of money for these laptops. I would think they would have better quality control. What a joke!
