I'm new to the forum, but not to MacRumors or Apple. Last week I bought the new iMac 20" 2.4Ghz. My previous mac was a G4 Quicksilver. a HUGE upgrade and I couldnt be happier! True....there is a color shift but it doesnt bother me. I'm a motion graphics designer and video editor so color shift is not a real problem with me. If I do need to proof the output, I will connect to another monitor depending on the project (i.e. doing video work will connect to a tv for title safe, color, ect.). The screen is glorious and its blazing fast! The graphics card is amazing also. Since I don't play games on my mac and only use it for work, the GPU works perfectly for what I need. So the bottom line: I couldn't be happier with my purchase. And if you do Motion Graphics/Editing, I would recomend this mac hands down!
