i was hoping someone could help me out. i've just started college and need to get an Apple. i'm seriously thinking about the PowerBook, but i'm going to use it for Photoshop and other stuff like LightWave and Maya. would it be worth waiting for a faster PowerBook to be released or should i buy now? also, does anyone use a PowerBook for this sort of stuff, and when doing 3D stuff is there a big difference between the 550 and 667MHZ? are the current PowerBooks ok rendering etc. or would i spend alot of time watching the clock? any help would be appreciated!
