Hi There, A friend of mine wants to get a new mac for all his audio-editing projects (he mainly uses Garageband but really pushes its limits). He's willing to spend around $2,000 to 2,500. He's eyeing the 27" iMac (for it's massive screen size) but wonders if the recently bumped MacBook Pro's would be better (downside would be buying an external monitor and smaller HD). Unfortunately he isn't happy to wait until the next iMac refresh, so that's out of the question. What setups should he consider? How much RAM should he get? I appreciate any and all advice, the audio-editing world is foreign to me and I want the best for him. Thanks all.
