This is the newest rev. w/ the scrolling trackpad and increased backlit keyboard. Specs are as follows: 15" Screen 1.5 Ghz G4 1 Gig of Ram (512 of apple ram, 512 Crucial) 80 Gig HD Superdrive (latest model) This awesome Powerbook is only a month old so you have the remaining 11 months of applecare plus the ability to still buy 2 more years. It's in NEW condition with no dead pixels on the screen! Absolutely in perfect condition! I'm selling because I've decided to go with a desktop instead for heavy duty video editing. I have a 100 percent feedback rating on Ebay (user name MaxMsh) and I'm a verified business member of PayPal. This computer cost me 2300.00 a month ago and I'm willing to let it go for 2100 plus I'll pay shipping if you're in the lower 48 states. I will only sell and ship in the U.S. If you're in the market for a new PB here's your opportunity to get the latest model at a discount!
