I got 2 Air 2's and it drove me mad checking for dead pixels. The first one I kept thinking I could see one, top left. When I rotated the iPad I couldn't see it! Had it for a week (bought last Wednesday), sent back today. Thing is I couldn't say for sure I could see anything. I think if you do have a dead pixel you'll see it. Especially using the white screen with brightness full up. Also, one last point. If you carry on looking you'll convince yourself there is one! Have a quick look, if all ok, forget and enjoy!
