I have a 667 and have had no paint problems. However I hardly ever use it without an external keyboard, mouse and monitor (both at work and at home). This leads me to believe that all the problems with Titanium colored paint must be because of human oil and sweat contact. Also, heat may be an issue. In this regard I have a small portable fan running immediately behind my Powerbook keeping it cool at all times. As a result, there is not a mark on my TiPB (which should make it a bit more valuable when the time comes to trade it for a 1 ghz dream machine!) jg
