I have an ibook G4 14" 1.42 GHz/ 1.5GB RAM and I have noticed problems from the moment that I got it, but I thought that it would still last. Sadly, it doesn't seem like I'll be keeping it much longer. The Firewire port has never fully worked and now it doesn't even recognize FW devices to send power to. The USB ports are off and on as far as working and now mostly off. The "Q" key and the "Delete" key suddenly stopped working, and WiFi drops often. SO, I think I'll be selling it for parts or something since the RAM is the thing in there that's worth the most and otherwise the computer works just fine for internet via the ethernet port and otherwise. It's a sad day, but luckily I have an iBook G3 900MHz and 640MB RAM to go to for my mobile computing purposes and extra cases so I can have custom looks.
