**It's just a crazy deep scratch... took the cover off and no sign of defect! Case closed - well sort of.... "WHO SCRATCHED MY MAC?" Just noticed this crack on the bottom of my macbook pro 17 late 2011. Is this normal? I'm new to Mac and always take such good care of it - so this makes me worry that it will keep getting bigger on it's own and the corner end up falling off. I contacted Apple, they said "accidental damage" (but seriously...) and go to the closest repair place and they'll tell me what it will take to fix it. This seems like this would be a material quality issue with the aluminum. Anyone else see anything like this? I'm interested in how this is handled, it will help me decide if I want to buy the applecare or not.
