The basic idea, yes. But on the other hand, my girlfriend's macbook (white plastic) discolors easily, and even worse, cracks around the edges. It has tiny spacer bumps on the lid that press into the keyboard layer plastic all around the outsides. It then cracks a millimeter around the edges of the plastic that surrounds the keyboard tray.

Anyway, Apple does it well, but has room to improve. However, they get my money because they keep trying to improve.
