I will use the computer mainly for DTP. Mainly Photoshop, Illustrator and InDesign. Usually it'll be all of them simultaneously, in addition to browsing the web, emailing, and Itunes. No games or motion. On the higher end I may be using 200MB large PSD's, but usually on the 20MB end of things, and I like working in InDesign with high quality display performance, whenever I can. I'm split between the 2.53Ghz 13" MacBook Pro (NVIDIA GeForce 9400M graphics) and a good high-end screen and the 3.06Ghz 24" Imac (NVIDIA GeForce GT 120 256MB). They both work out at around the same price. Plus with the MBPro I have the added portablity, which can come in handy every now and then. Do you think I'd feel a big difference in performance between the two given the processors and graphics cards relative to the kind of work I describe above? Thanks.
