Just picked up a new MBP at the 5th Avenue Apple Store. It seems fine, but if you look closely toward the top of the display, maybe 2mm below the edge of the LCD, the display in that area is slightly lighter than everywhere else. It forms a light line about 4-5 pixels across that runs across the displayer past the middle, but doesn't quite reach the left side. Is this common with the new LED displays on the MBP? My old MBP was a RevA with the regular display and didnt have this line. I am thinking of going back there to return it tonight, but I am wondering if they will give me a hassle if I ask for an exchange. What should I do?
