also the newest macbook pro will be able to have up to 4 Gigs of RAM in it which will be a huge plus for on th emove editing, but personally although I have yet to use this new macbook pro, I have always been bummed on editiing even on the best laptops. They are slower and bog down, and mostly the thing that bugs me after working on two huge dual screens I cannot get over the crammed look of FCP. Really that is what bothers me, although I am very interested in this thread because I am thinking about purchasing a new laptop for on the road editing, although I only use DV, I am using an extreme amount of high-level efffects that take time to be rendered. On my macpro with 9 Gigs ram I am flying still but on a laptop I am afraid it will not be worth the time cause it will take so much longer, and end up being a waste of money
