I have a 15" unibody pro, and when it's all cleaned and polished it looks absolutely stunning...but quickly it becomes covered in smudges, fingerprints etc.... It shows every little spec of dirt. It drives me insane, I'm constantly trying to clean it. It's so bad I'm considering selling it and buying a white one....unless the white one is just as bad. From what I remember owning an older white macbook, it's wasn't as bad.
