So I have a new 15" MBP scheduled to be delivered tomorrow, and am wondering what uses I could get out of my old 2009 model. The old one has 8 GB RAM and a 120 GB GSkill Phoenix Pro SSD. I have considered selling it and getting a Thunderbolt display, but with being unable to attach my 27" iMac to it for double large screen goodness, the idea has sort of fizzled. What do you all think?
