Hi guys. I've been surfing these forums for several months now trying to figure out the right Mac for me. I ran into this ad online ( http://charlotte.craigslist.org/sys/2905811670.html ). The seller has agreed to take $850 which seems like a decent deal. Before taking off I wanted to ask you all if there is anything I should look for when checking the machine out? Also, how can I double check that it has an SSD? EDIT: I think I figured out how to check this (http://machicolate.wordpress.com/20...-your-macbook-air-has-the-faster-samsung-ssd/ ). I apologize in advance for my n00bness, any help would be greatly appreciated. Thanks everyone.
