Okay so I might be getting a powerbook g4 as a back up computer to my pro. But I want some opinions on the idea first. Do any of you guys use one, I know that they aren't Intel macs so are they obsolete? Just what are your opinions on them. here are the specs 15" Powerbook G4 1.33ghz 2 gigs of ram 60 gig hdd (will upgrade that if need be) comes with the osx 10.3 The battery is pretty shot they say it lasts about 30 minutes; I will just replace it if it's not to hard to find one. Thanks for your time.
