Hi, I currently have a first generation core dui 2.0 MacBook, and am looking to upgrade it to one of the new unibody ones. I'd probably choose the high end MacBook, but I am starting to get into creating music. Is the lack of Firewire on the new MacBook going to create lots of problems? I looked on Apple's UK store and the majority of music equipment was USB based. Is Firewire just mostly used with video editing? :S Sorry if this has been asked before, I just want to make sure I'm not spending a few hundred more for a Firewire port! Thank you!!
