I'm getting a laptop before I move and can't decide if I want an Apple or IBM/IBM clone. The studio I will be working in has a nice Protools HD rig and I want to be able to fly files back and forth ie record drums on the big system transfer the tracks and tool around with guitars and other stuff on my own. I have not used protools much but know most people perfer the macs. I found an iBook that looks like what I need for $1300 but I can get a similar IBM for $800. So my question is does protools run better on a mac or enough to make it worth the extra $500 to get the mac?
