I'm looking to by a Mac laptop (preferably the MacBook for the size and cost), but I have some concerns about the graphics. I'm an engineering grad student so I spend most of my time in Matlab, but I also use a bit of Illustrator and Photoshop. I use Illustrator mainly to make posters (A1 size with gradients, drop shadows, linked jpgs and whatnot). My Photoshop use has thus far been pretty limited, mostly cropping, scaling, touching up my photos. Does anyone have any experience running Illustrator (and/or Photoshop, Matlab) on a Macbook? Are these the kind of tasks that are suitable for the MacBook or would it require the MacBook Pro? Thanks!
