So I have the last revision of the 12" Powerbook G4. I bought it when it first came out, maybe ~5 years ago? Aside from needing a new battery and AC power cord, this lappy has been running like a champ for the last 5 years. No problems. How long can I expect to keep this laptop going before it "craps out" ??? I'm saving up for a new Macbook in December... one more month to go!
