Hey there, Last night I sold a 2009 mac mini (base model paid $550) that I upgraded with the 320gig HDD out of my MBP and 2gig of ram that I bought on craigslist for $15 bucks. I sold it for $750 since it had the same specs as the one Apple sells for $799.99+tax. I bought it in May and it was in pristine condition and it OS 10.6 on it, so he got a great machine. Anyways, should I feel guilty that I actually made money on a computer that I have used for the last few months and do you feel that he paid a fair price? thanks.
