I picked up the base model Retina MacBook Pro when it came out, and although I really love it, I plan on selling it. I recently went on a trip, but I wound up not bringing it because I thought it would be too big and heavy. I currently use it as a desktop replacement at home, and 15" is just a little too small, so I'm thinking of going with a 13" MacBook Air and a 23-24" external monitor, that way I get the best of both worlds. I haven't sold anything on EBay or Craigslist in forever, not to mention that we are talking about a $2000+ device. My rMBP is in mint condition, and I have all the original packing with a leather case. What price would you recommend I list it for, and where should I try to sell it?
