I'm a Mac user (/Mac lover), so I was wondering if there are any major limitations to using a MacBook Pro to run required programs for school. I'm enrolling at Harvard in the fall and their guidebook doesn't suggest one over the other, but rather states, "The differences are distinct, and one size does not fit all: but both types of computers have been successfully used by numerous students at the GSD."
Also, how essential/convenient is it to have a large screen? 15"+? 17"+?
