Though I may wait until January (hopefully after new machines are available), I'm trying to decide between a MacPro and an iMac 24". I'm a graphic designer and I do a lot of photoshop and web work. I have always used towers. My current G5 dual 2.0 just suffered a dead power supply and I've got the itch for a new machine. I never considered an iMac for my work, but my tech guy suggested one. Thoughts?
