I am a graphic design teacher. I have been told that the powers that be are updating my teacher machine for next year. My tech boss asked me if I wanted to spec. my machine...imagine that. My quesiton: With the educational discount, under the $1900 budget (as close as possible) do I load up a 12" PB SD with memory etc., or do I opt for the 1.3 15" PB? I have a super drive at home, so that is not one of my worries, but wondered what you would do given my (very nice) predicament.
