Today my 2009 15" unibody macbook pro was stolen out of my apt. after realizing that I have next to no chance of getting it back I realized that I should start thinking abuot replacing it. I was wondering about what improvements have been made to the MBP line and what my best value is. I don't need anything better than what I had, and am willing to go smaller as long as I'm not sacrificing huge on performance (i play a few games on steam like portal and left for dead, mine craft, nothin too intensive.)
