Bought a 13" Macbook pro from apple in May 2010 and just last month I started to notice these lines. They seem to only stand out in a dark screen like while watching a movie or playing certian games. I've been babying the thing since I bought it do you think it would be something that would be covered under warranty? Just wanna get an idea of what the "genius" at apple are gonna tell me before I bring it in. Thanks
