So I noticed today that I have a very thin line that runs the entire height of my screen. It's really noticeable when you're running darker gray things (like Garageband and iMovie) the interesting thing is that I never noticed it until today because it was conveniently along the divider line (and I decided to drag iMovie to another space and noticed it). I'm thinking it's a backlight thing or a LCD thing. I haven't noticed it or tested it on Win7 to see if for some reason OS X is making it appear. I can't take a screen capture of it (obviously), but when I get back from my university, I'll try to upload a pic if it's not resolved by then. Do you think the store will replace it? Applecare? EDIT: The picture is my attempt at showing the problem with a darker, thicker line. That's not actually the exact picture. Think a few shades lighter.
