Hey everyone I recently got my rMBP 2.3/16/256. I am still using my old 2007 MBP 17" as my main computer hooked up to an ACD. I put it up for sale on craigslist for $750 and I have a buyer who wants it right away. Now I am thinking if it is worth this much or just keep it as a backup computer. Do you guys think its a fair offer price? It is upgraded to a 120 GB SSD and I am also throwing in a pair of headphones. This was my plan to begin with, hence why I bought the rMBP but now I am hesitating because I am too attached to it. Should I sell? Thanks!
