Hey guys, I will be attending medical school in the fall and I was thinking about upgrading my 2011 MBP 13in. I envision a set up where I take a MBA to class and then, at home, use a separate monitor to study. I will be checking email, using the internet, watching videos and listening to lectures, opening textbooks and searching through large PDFs (no photo/video editing and nothing too resource intensive). This relatively "light" load is what has lead me to a MBA over rMBP. However, I was wondering if using a separate monitor changes anything. Does ti make the usually non-intensive things more intensive? or does it depend on the resolution of the eternal display? If so, would a rMBP be more ideal? If not, would a 11in MBA be just as good as a 13in MBA? Thanks for the help!
