Hello guys, I bought a Macbook Air from the Apple Store back in July. Today I noticed that the place where I usually rest my hand has suffered some damage (http://i.imgur.com/TQUr7dO.jpg - it looks a lot worse in the pic than it is irl). I've read in several forums (including this one) that this might be caused by a special reaction that takes place between my sweat and the computers' aluminium. Not sure if this is the case, but the truth is that it doesn't look pretty and in some occasions it actually hurts my skin. That said, I do have a few questions to ask, if you don't mind. 1. Do you believe this might be covered by warranty? 2. If yes, I could take it to an Apple Store. The problem is I really need my computer for the next five months and I don't have a replacement. Do you know if there's anything I can do to solve this problem (other than taking it to a store, that it)? 3. At least I hope it doesn't get any worse. Would cleaning the case more often help avoiding this situation? Thanks for your help! All the best.
