I purchased my first Mackbook Pro with one of the 2011 models, and I absolutely love it. I keep finding great stuff out about this machine every day. My initial plan when I first got it was to upgrade every year. I almost can't imagine letting go of such a nice machine, even if it is to upgrade to a newer one! Do any of you have a difficult time selling your MBP's when you want to upgrade machines? It's going to drive me nuts the couple of weeks I'm without my MBP once I'm in the process of upgrading at this point. I have always had a habbit of falling behind with old gear because I don't want to give it up.
