Hi everyone, I am planning on selling my Macbook Pro on Craigslist in order to get a new Macbook Air. I need some advice on how much I should sell it for. Here are the specs: 15 inch Late 2009 Macbook Pro 4GB of Ram Upgraded harddrive 500GB 7200 RPM 2.8 GHZ Intel Core 2 Duo. The computer is in used condition, but it has a small dent on the top right hand side. It is going to come with all of the original packaging, the latest Mac OS X, the latest iLife, the latest iWork, Microsoft Office 2011, and an incase case. Thanks for the advice!
