It's a late 2008 unibody aluminum 2.0 GHz Intel Core 2 Duo, 2GB memory, 160 gigs of storage. the first aluminum macbook, not a pro. It has been upgraded to Lion, but the iLife is '09. It has about a 2 hour battery life, and the battery is removable w/ replacements sold on the apple store site. It is a little slow, and often has to be restarted from sleep because it has problems waking up. I have the original box, cords and discs. The apple store recycling program estimates ~$300 that they'd give me to trade it in, but could I get more by selling it elsewhere?
