I'm buying a macbook off Craigslist tonight, and while I dont think the guy is trying to rip me off, as he's doing a fresh install and he's not a kid, but you never know. Aside from just watching the computer boot up, is there anything else I should look for, test, or ask about before I hand over the cash. (I'm new to the mac thing, and suspect I'll be here often once I start trying to figure out OSX) By the way I'm getting a 2.0 Duel Core with 2 Gigs of RAM for 700$. Only an 80 GB HDD but I dont care as I'd be upgrading to 320 no matter if I got it new or not. This seemed like a fair price to me, anyone think it's a bad idea?
