I have the opportunity to buy a 17" PowerBook G4 1.5Ghz/1.5GB RAM/80GB in pristine condition for $50. The buyer states the battery lasts about an hour. I'm not sure what I would do with it, but it seems like a cool piece of apple history. What do you guys with G4's do with yours? How well do they handle the internet? How do you think this would compare to my G5 (see specs).
