Bought one of the 2.6ghz MBP's about 4 days after they came out. Had yellow screen upon arrival. Replaced. The top part of the screen was dimmer. Replaced. Now the left side of the my screen is brighter than the right, i.e. when I'm on a website like gizmodo, the blue on the right side of the screen is darker than the blue on the left side.
This is annoying. I had to save money and buy a nice 500gb hard drive for backup purposes, apple replaced the hard drive on the second time around - they thought putting a new HDD in my MBP would fix the problem I guess?? It didn't. Also, there is about a quarter inch of horrible backlight bleed on the bottom of the screen and the screen is not centered inside the casing, It's all the way to the left.
Perhaps the fourth time will be the charm... 😡
