So I have a scratch in the upper left corner of my one-month-old Retina MacBook Pro. I can't for the life of me think of how it happened. I can't tell if it's a scratch or a crack, but I take really good care of my electronics and have been babying the new computer. I took it to the Genius Bar and of course they said it's cosmetic damage so it wouldn't be covered under warranty. It's currently being sent out for a different issue where they are replacing the logic board and top case, which makes me a little uncomfortable because it's only one month old.
