I have a 13" MacBook Pro that I purchased in early 2011 (literally the day that the new models came out). It's the entry model; 2.3GHz i5, 4GB of RAM and a 320GB hard drive. I found a new 15" for about $1300 in August of this year so I quickly bought it and retired the 13", which I haven't gotten around to selling until now. Even while I had it, I used the MacBook in conjunction with another computer, so it really hasn't seen much use. I still have the original box and the original pamphlets, and I will be selling it along with a brand new adapter which was never removed from the packaging. I'm looking at putting it on Craigslist, and was thinking $800 seemed fair. Does anyone have any suggestions for me? Thanks!
