So guys, I was really disheartened by the update to the 13" because this was the model I had intended to get a few months ago. Now i'm starting to lean towards the 15" because of the processor (mainly). I'm looking to use it when I go to study Law next year so the 13" would be great for portability and I already have decided whichever laptop I get I will also get an external display because with Logic i'd like the mixer open in the smaller screen and the arrange window in the large screen. The real question is, which one to go for 15" or 13"? Which one will be the best for using Logic Studio 9. Thanks in advance.
