At the computer repair shop that I work at, a customer recently came in to bring in what she described on the phone as an "old Mac" for recycling. She brought in a decent-shape 15" 1GHz AlBook! There's a couple fairly noticeable bruises on the lower corners of the screen, but the body is overall in great shape. It also has a nearly-new Newertech battery in it! It was stock with a 60GB and 512MB RAM running Panther; I've bumped the RAM to 1GB with what I had laying around and installed Leopard, which it runs like a champ! I used a 12" PowerBook G4 as my primary notebook all through college, so it's wonderful to have one around again. Shout out some love for your G4!
