I'm looking for a laptop that will get me through my last year of grad school in architecture. I'll need to use 3d modeling, acad, adobe creative software etc. Do I really need a macbook pro or can I get away with a macbook (and maybe an additional monitor)? I bring my laptop between the studio and home offices and otherwise travel with it, so size is somewhat important to me. The screen resolution and graphics card are better in the macbook pro, but I'm trying to determine how much that would impact me. I care about making nice renderings from my 3d models and having a fast computer but any improvement would be better than the dinosaur toshiba I'm working on now.
