I love my new air. It simply works. Good battery, solid performance with pixelmator, but has a problem. The keys seemed to be a little finicky the moment my post purchase high wore off. They were all solid, except for the 3 key. It made a crunchy noise when pressing it. I took the key off, and the plastic bit which snaps it into the scissor mechanism was cracked. I can put it back on, but when pressed too low down on the key, it seems to lift it out of the clips or something. It is obviously broken. Should I just take it to the apple store? Will they not replace it if they know I took it off? I know I have a one year warranty, so it should be covered. I can just go in and at worst pay downwards of 30$ for a new key cap, right? Well, at least I hope so. If this problem persists, I will honestly complain to apple.
