Honestly I dont know how it got cracked. I used it at my worksite today, and brought it home in a backpack. Ive carried it around in that backpack hundreds of times. It didnt get roughed up or anything today, and I was just shocked the next time I opened it to find it cracked. I wouldnt expect them to cover it, but I know Apples customer support has a very good history, so I was wondering if anyone else had ever been in a similar situation and what had happened.
