I picked up this 2008 macbook air today for the fantastic sum of £90 ($150). It's in great condition, a couple of very slight scratches on the bottom and a very small dink on the trackpad button, other than that it's like new. It was advertised as non-working as it was stuck at the grey apple logo screen (I suspected an update loop, I was right). It's up and running now and I'm in the process os updating it, I'm upgrading it to lion now and I'm going to try out the Mountain lion hack to see if it's stable. How much do you think I could sell it for? It's not boxed but comes with power cable.
