Im considering selling my Macbook Pro to upgrade. It is in perfect mint condition and is still covered under Apple Care until July, 2013. It has been kept in an iPearl cover so it does not contain any scratches. Specs are: 13.3/2.3 GHz Core i5/2X2GB/320/SD/GLSY Model A1278 Early 2011 I still have the original box. Can anyone advise me on what I should ask for it or approximately what I could get for this computer? Thanks so much.
