Hi, So by tonight, i'm either buying a mac pro or this new macbookair thing. This leaves me the question of what to do with my old 12" ibook G4 that has been used all day everyday for 3 years! The battery is so dead it will run for about 3 minutes before it cuts out! I was wondering what i could do with it - i'm thinking if turning it into some sort of jukebox to just play itunes. It only has a 30GB HD so i was thinking i might put in an 80GB drive perhaps. And treat it to a new battery. Anyone got any better ideas of what to do with it?
