Hi, I got my 13 inch MBA yesterday There are 2 issues were found, and might be related. First is that the bottom case bulging. Right side of the chassis is obviously(but still need to compare carefully) thicker than the left side causing it sometimes touching or scratching the surface of my desk. Second issue is that the battery life is considerably shorter than the specification which is 7 hours. After a full charging cycle, with 50 % brightness, it shows me only 3 hours remaining. And When I actually start using it, the battery exhausts even faster than that. Less than 2:30 hours So I highly doubt there is some problem with the battery, but I cant open it Could you guys please tell me your opinion about that or if it happens on your machine???? Any reply is highly appreciated!!!
