Hi, I bought my macbook about 3.5 weeks ago (25 July, directly from Apple store) and there are two very thin cracks forming on the case. They are both forming on the front (same panel as sleep light and IR sensor). One is about half an inch long, but the other runs from the magnetic part (where the lid closes) all the way to the I/O port side. I've treated this laptop very well and have NOT dropped it. It rarely leaves my desk. Last night, the crack that is currently VERY long was shorter than the other, and it has not left my desk since. Is this normal (I assume not) and should I take it to Apple? School starts tomorrow for me so being without my laptop for any more than a week would not be good. I'll try to get some pics up later tonight.
