Well, I'm not going to go through that whole thread, but my Mini runs PSCS3 just fine. Aperture runs well, too, rendering my 30D raw files in about 2 or 3 seconds. For 2D work, the mini is adequate. If I were a pro, I'd be using a Mac Pro. I would not use a new iMac with their glossy screens, because many of the colorimeters have real difficulties with them. I just don't trust them - I'm very happing with my Mini and its matte Samsung display.
