Just received a new 13" MBA last week. After using it a few days, felt that the trackpad wasn't responding very well, so I took it to the Genius bar to have them check it out. They looked at it and compared it to a couple of the MBAs out on display, and agreed it was definitely messy, so they sent it in to have the trackpad replaced. Got it back yesterday, and the trackpad is more responsive, but now I find that I can't get secondary click to work on the left corner, but it did work on the old one, although needed a really hard press. I tried switching to secondary click on right corner, and it works. I'm still feeling that the trackpad isn't working right and have made another appointment at the genius bar to have them look at it again. So is it common for the MBAs to have trackpad issues? I'm wondering if it's a common problem due to the case being so thin there. This is my sixth Mac since I switched from PC to Mac in 2005, and the first one to have any hardware problems at all! I started with an iBook G4, then added a G4 mini, then later a 24" iMac, then a 13" MBP, then a new MBA last fall. None of them have had a single hardware issue. I'm just hoping the trackpad isn't going to be a chronic problem with the new thinner MBAs since I love the trackpad on the MBP and it was the reason I bought the MBP in the first place since it was so much easier to use than the iBook trackpad where you had a separate bar to press for click.
