I'm looking into buying a mac for Design and music production. Ill use indesign, ps cs3, illustrtor cs3 and pro tools for music. Is it a big difference between these two macs besides one of them are portable? Will a macbook pro + 24'' monitor be a iMac 2,8 with a portable option? Is the 3,06 MUTCH stronger than a 2,53 mbp? I cant decide, i've sold my pc's, and need to be sure of what to get. thx!
