I'm a photographer and musician, mostly the former. I have a ton of 10MP RAW files that I run through Adobe Lightroom and CS3, and I do the occassional music recording in Logic Express (just of myself, so I don't need to do simultaneous multi-track recording). None of it is pro work, though I do sell the occasional print, and may do more of that in the future. With my edu discount I can get the 20" iMac w/500GB HD for $1489, and max out the RAM for about $100 or so more (OWC). I can deal with the single HD bay by using externals (not too concerned about clutter), and I'm not too worried about the glossy screen because I already have a 19" matte LCD that I can do my photo editing on. I'm just not sure if I'll ever wish I could stick more than 4GB of RAM into it. For about $500 more I can get the new quad Mac Pro, stock (with a student ADC discount), but I'd then have only one monitor (the aforementioned 19" LCD), and RAM is more expensive (don't know exactly the cost yet, as OWC hasn't added the new Mac Pro memory, but going on the previous Mac Pro it's likely to cost more than iMac memory). Are my needs enough to justify the extra $500, lack of a second monitor (until I can afford one), and more expensive RAM upgrades? I'm certainly lusting after the Mac Pro, but I'm trying to be realistic. After all, I'm a grad student and could certainly find use for an extra $500 in my pocket. I'm also coming from a 1.42GHz G4 iBook, so I know either one will be a huge upgrade.
