Hello all I am seeking some advice on this issue I'm having with my MBA. As recorded in another thread, I have had this horizontal line that appears and then disappears on the display. The first Air I had received two repairs that didn fix the issue, so Apple replaced it. But this Air had the same issue, so after many calls to AppleCare trying to convince them that this was indeed a hardware issue, they finally agreed to give me a refund which I used to get a 13' Air; this Air has the same issue. SO, now I am stuck with my THIRD Air with the same issue. I am trying to get Apple to replace it with a Pro. However Apple says that they won't replace it outside of the product line, they would just give me another Air. I don't want to get a fourth air with the same issue; so at this point shouldn't Apple just replace it with a MacBook that doesn't have the issue? Any suggestions on what I might be able to do to get this resolved, to possible persuade Apple to replace it with a Pro? An AppleCare advisor before I got the second replacement told me that they would replace it with a Pro if the second replacement didn't work, but he must be the only one who thinks that way. Anyway, what should I do????
