Oops I meant Retina Mac Book Pro! Last years model is $230 cheaper. I only see a difference in speed: 2.4ghz vs 2.3 ghz i7 processor. I read internal components could be upgraded, but I dont know if they are major components..what do you suggest i go with? ---------- BTW I have a 2009 MBP 15". Love it but ready for SSD , Retina, and faster processor.
