So the trackpad on my mba is broke. Not the whole trackpad, specifically the button. It's still functional and I'm able to click on things, but the best way to describe it would be to picture a teeter-totter ride. If I click on one side, the other side pops up, if I click on the popped up side then the opposite side will sink down (well below the surface of the area around the trackpad). And if I click anywhere in the middle, it may or may not work. I am already in the process of having it replaced, through apple warranty. I just wanted to see if this is a common break in the mba, and others have had similar issues with the trackpad?
