How do you figure that? Some pros, like web designers, could probably do just fine with one of the new iMacs. But for data throughput-intensive work, like 3D or video, the faster the machine, the better. Yes, you can do this stuff on an iMac, but pros in studios who do the higher-end stuff need the most power possible. An iMac ain't it. I can guarantee that when the next CGI-intensive commercial or movie comes out, it will not have been done with iMacs, 800MHz G4 or not. If nothing else, the 15" monitor's a hindrance. (Some programs, like Softimage e.g., require a very large screen.) And, when you can get maybe 3x-4x the rendering speed out of a dual-Athlon for a 67% higher price, why would you go with an iMac?
It all depends on what you want to do. The new iMacs do have a decent chip in them now, and the monitor's spacious enough for lots of graphics (and other kinds) of work. But for the high-end stuff (read: film and some video work), hi-powered towers are needed.
One bit of optimism I have for this whole thing is that Apple is usually very cautious about cannibalization. I can not see the current MTs lasting too long in their current condition. They're either going to see a major power boost or they're going to have to have a price drop. Either way, it can work toward our advantage.
Now I think Apple should have announced, at the very least, MT price cuts and/or promos this past Monday. But even if they're late, I think they'll be announcing SOMETHING soon.
