I'm going to York University for film production, and was wondering what sort of setup I should be looking into. To note, I already have a 2010 13 inch MacBook Pro 2.4 ghz C2D. Here's the question: Should I buy a fully specced iMac 27 inch? (This paired with my older 13 MBP) OR Should I buy a fully specced MacBook Pro 15 inch? (Portability factor) Any advice is much appreciated.
