Hello! I will now buy my first Mac, I will go for the new MBP 15". But i need little help what i should buy. I will use it for Photoshop, Dreamweaver, Maya and maybe some windows games. I choose between this: 1: 15" 2,2ghz standard model + 20" cinema display. 2: 15" 2,2ghz 4gb ram. 3: 15" 2,2ghz 2gb ram 160gb hdd 7200rpm. and last standard 15" 2.4ghz model. I did also look on this backpack from Brenthaven.
