... for starters I'm not exactly happy with this. I had a broken fan problem and i brought in my air to get it fixed and I told them to reformat it since I don't have any means to format it at home. Well they fix my fan problem, a tiny tab or ribbon is sticking out of the case though, no problem with that. I just used something and pushed it back in. Now the big problem is they seemed to install a desktop leopard on my air. I can not change the settings of my trackpad (meaning no right click, no tap to click, mouse gestures) and none of the function keys work on my air. The keyboard illumination doesn't work either. I even have a little icon to eject a cd from my air . Is there anything I can do to get my preferences back as it took me five days to get my air back and I'm not really in the mood to wait another week for it.
