hey I have a macbook that has a really crappy display from the start. There is backlight bleeding an inch in diameter on every side. But to make matters worse, there is an evident bleeding on the bottom near the centre of the screen and below it, its like a black spot of some sort, since the brightness is lower. It kind of looks like light blobs. What would it take for me to replace this computer for another. Is it possible to negotiate with apple store managers, possibly paying a difference or something? Any help would be appreciated.
