Well I just had a rough time with the Apple Store, which was diffused by my girlfriend (gotta love her). I had just bought a Rev B air from a reseller, and I didn't particularly like the quality I got it in. It had the lines issue, the infamous wobble, and also black grease that formed on the top of the display bezel. I didn't know whether I would get this repaired since I bought it from a reseller, but I tried anyway. Needless to say, my first visit to the Apple Store was not very pleasant. They actually didn't do anything but flexed the aluminum to fix the wobble. They tried to clean the grease with alcohol, and that didn't work, so they said that they couldn't do anything for me. I'm not one to deal with irritating people, so I just left before I fumed at the guy for handling my Air like it was a cheap whore. I told my girlfriend about it and she was pretty mad that they did that (also she has the black spots on her display bezel so she wanted to see what Apple would do about it). Next thing I know, she was bringing my Air and hers to the next Apple Store and I have two Genius Bar Work Authorization papers for repairs. They apparently are going to replace both our macbooks' screens, and they ordered a new bottom for my wobble. I swear, so many things take a woman's touch. I just wanted to share my experience so that others know you can get the wobble and black smudge repaired. I've read several forums that say otherwise. One thing that seemed to help though was having that one Genius who flexed my laptop. They said that normally, they would make customers pay for a replacement bottom, but since the last Apple Store fudged with the bottom already, then they had to replace it for free. I'll post on for further experiences.
