langurmonkey: OR are laptops one of those things that lose all value, the second you buy one? If the answer to my first question is yes, where is a good place to sell your used laptop? Craigslist doesn't seem like a good place...
I'm on a refurbished laptop (refurbished just being the new fancy word for used) right now, in fact, a highly portable 11.6" ASUS. Used laptops aren't really where you go for gaming power, but they're pretty cheap and a good way to test out something you're interested in (in this case, touchscreen laptops plus Windows 8) without going in more than a few hundred bucks.
Craigslist is probably one of the top places to offload your used stuff, but the only refurb computers I've bought were from TigerDirect. I have no idea how you'd go about selling a laptop to them. For selling, yeah, I'd go with Craigslist or maybe, dimly maybe some local computer shop if there's such a thing near you.
