I purchased this MacBook Air (after returning my 2.8 i7 MacBook Pro after 3 defective replacements as an intermediate computer until sandy bridge) and I noticed that at about a 45° angle there is a white spec in the screen but straight on it is not visible. It's not that annoying but now that I have noticed it it will be annoying me. Also on this Air the computer wobbles. Should I get a replacement? I really would choose not to because I love this computer (A LOT more than my previous MBP) I seem to be such an unlucky person to get so many defective Apple computers :/ Thank you [Attached is a picture of the spec] [UPDATE] This computer also creaks. Could this be fixed by reseating the bottom plate with the 5-point torx drivers I bought?
