guy, after a hard suffering 6 months (my rev C Pbook was stolen 6 months ago) i'm now able to buy a new machine. I'm starting an Audio Production Master in 2006 (as i mentioned in another post) and i need a powerfull machine to run a few recording software and a few things. i'm thinking about mbox 2, (pro tools, Logic, etc... software-wise) or an M-Audio Firewire 410 interface (pro tools m-powered, logic, Ableton Live, etc. software-wise) all this will be run from an External 200 gb firewire drive (7,200 rpm) the PERFECT machine would be an iMac G5 20" BUT, i need portability since i'll be leaving my country and a student life needs portability. (besides in a year or 1.5 years i'll try to buy a new, faster imac, with bigger screen) do you think a 15" rev E (1.67 ghz, 1.5 gb Ram) powerbook will do the job for a year or so?? without it being too jumpy/latency? Thanks.
