Man, that's gotta suck. I was lucky, my second air had a great screen, pure luck i guess.
Btw, how did you notice a dead pixel? I'm just wondering if there's a certain way to make it easier to notice or is it very obvious?
Thanks.
The retina display certainly makes it harder to see dead pixels (which is a good thing). I did a Google search for a white background and saved it to my camera roll on the iPad. Then I viewed the white background and stretched it out in the photo app so that it filled the whole screen. From here I can easily see defects such as screen yellowing, faint lines, and dead pixels. Some dead pixels will only show when a certain color is displayed, so you can try colors other than white. Many people will say "don't go looking for them", but my feeling is that you're better off finding them within your 14-day return period than after. Unfortunately for me, once I find one, I see it everywhere. My eye just goes straight towards it and it drives me crazy.
