I was handling my MBA last night. I turned it over to look at the bottom, and there's a screw missing. Got out my screwdriver and check the other screws, 3 more were quite loose. Just a caution t check your own MBA, and see what yours is like. So I called my local Apple Store, we have no screws. Called AppleCare, we don't have any screws to send out, we can't do that. But we can set you up with a service ticket. I have to say that it is absurd to send my MBA in for repair, when all I need is a screw. Anyone have an idea where I can get a screw?
