OH NO!
My MacBook is starting to show the exact same type of crack on the right side where my wrist lies.
I bought my MacBook last year in late April (2007) from my school's computer store. Should I bring it into an Apple Store? Or should I bring it back to the computer store at my school and contact AppleCare from there?
Also, I've forgotten: how long does the warranty last for? I'm guessing mine is no longer under warranty. So will it cost anything to ship it in or to get it fixed at an Apple Store?
