Used Mac Powerbook G4 from about 2005 era.
1GHz, 512MB Ram, Superdrive, Microsoft Office (Powerpoint, Word, Excel, etc), Quicktime, All the original apple programs, tons of iTunes music, Adobe Lightroom, airport card, dashboard, 80gb HD, etc.
I've been the only owner of this computer, and I've taken pretty good care of it. The Monitor was replaced after dead pixels showed up about a year into owning the comp, so the screen is still running like a champ. The hard drive failed about 2 years ago, and that was fully replaced. The comp was dropped while in a sleeve back in school and there is a ding on the outside casing (doesn't effect performance whatsoever). One other thing of note: the power adapter crapped out on me about 2 months ago so I picked up a new charger. The battery is in "ok" condition. It holds a charge while running multiple programs for maybe a half hour. So I would suggest replacing that, and you can do so on ebay for about $50.
Other than that, the comp has treated me great. I would be keeping it but need a Mac for work that can run both OS X and windows. I have all the original manuals, box, operating software, cables. For the price, I'm open to offers. The cheapest I've seen these for used is roughly about $475. I would do $425 plus shipping. I can also throw in a free 30gig 1st gen Video iPod that has a ton of music and ski teasers on it.
I'll be sure to have pics up soon. Thanks for looking.
