My TiBook is fine...... like most I treat it as if it was my own child.......
Could it be something you cleaned it with??? I use Mr Muscle Glass Cleaner on mine (the green stuff, although u might not have it in the states) and clean it once aweek, to get greasy paw prints of it, also has fixed the problem some of the Rev A TiBooks had with the PowerBook G4 logo rubbing of on the base of the mac just above the mute key...... I don't have that problem any more......
Not had any problems at all with the finish, have 2 slight surface scratches on the bottom of the TiBook by the vents caused by a zip, but nothing major.... mine passes as brand new.....
I look after it religiously as A: I like things to keep things in brand new, never used appearance.... (except my clothes) B; i know that I'll get top £ when I come to sell it in feb 03........
