I'll cut right to the chase: I'm a filmmaker/graphic designer/motion graphics artist looking for advice on which new Mac to buy. Right now I'm trying to decide between the high end 15" Macbook Pro and the new 27" iMac. (Quad core) I've been using a bottom-line 20" inch iMac for about 2 years. It's done the job but slowly. I don't travel a lot but when I have, I've missed my computer dearly. The way I see it the Macbook Pro is less powerful, but has the huge advantage of being portable. The quad-core iMac is a lot more powerful, but is tethered with a power cord. So I turn to you, MacRumors Forum, to help with my dilemma.
