I own a Pro 13", but I'm not going to risk taking it to school in the case of it being stolen/getting damaged. I would primarily take it to school just for light interactions so using a PPC laptop would be good enough. What I'll require is a computer that can run an AirPort card (preferably with one built in). I was thinking that either iBook G3 (Clam or Plastic) would be good enough, but I'm also looking into some of the PowerBook G4s. Where would be the best place to find one of these? Would a G3 work enough for Office and minor web browsing? I was thinking that a ClamBook would be the best since it's cheap and has a handle (and looks really awesome).
