Recently we heard of Khyros' very inspirational story of getting his top case changed by Apple Spain because of the discoloration which occurred around the area of the touch pad and the keyboard.

This issue was previously thought to be a cosmetic problem that was caused due to the owner's mishandling of the machine, making it not covered by Apple's warranty. But, maybe because of the increasing numbers of complaints about MacBook owners, Apple has reportedly acknowledged that it is indeed a manufacturing problem and not a cosmetic one.

Just like Khyros, if you're experiencing the same of problem with your machine, you're advised to call AppleCare so you can get your top case replaced for no extra charge. Apparently, the plastic in the new MacBooks are smoother to the touch than the previous plastic used.
