There is someone that wants to trade his 15" 2009 MBP for my base 2011 13" MBP. The specs on his 15" are 2.4 C2D, 4GB RAM, and dual hard drives (128 SSD Kingston S2 and a 250GB HDD). My 13" 2011 is the base i5 but I will be adding in 8GB RAM. He also wants to throw in $75 cash. His laptop is no longer under AppleCare too. Well, even if it was, the optibay HDD voids it anyway. Is this a good deal or should I pass?
