Damnit this just makes me want one even more, I think it's time I started planning a funding heist!
Even so, I am actually a little disappointed that the machine isn't actually black. Not a big deal since I have almost no room on my desk so it'll probably be going behind a monitor where I won't see it much anyway, but I love how it looks on the Mac Pro web-page.
I do wonder, as previous posters have mentioned, if

might be able/willing to offer a lesser configuration at the $1800-2000 price point to better bridge the price gap between the mac mini and this new Mac Pro? I guess I'm better off just getting a mini from now on as the graphic capabilities of this new Pro are way beyond my needs. I run dual monitors, but I don't need 4K at home.
I really wish they would; I mean, whenever the Mac Minis get updated the quad core models will most likely surpass my current 2008 Mac Pro both in processing and graphics, except in a few edge cases of course, so I don't really
need a new Mac Pro, as even the current quad core Mac Minis meet my current CPU needs.
However, if they had a cheaper entry level Mac Pro, maybe with 1gb FirePro cards or just a single 2gb card, then I would make the leap in an instant.
As things are right now the entry level Mac Pro is right on the edge of my budget, and I'd need to spend at least an extra 10% on a hard drive enclosure for storage capacity, plus either a new external sound card or a firewire adapter for my current one…
While I could maybe make back a bit of it on selling off my current Mac's parts, plus another older machine I should really get rid of, it would still end up leaving an uncomfortable hole in my accounts.
I was hoping that the reason Apple announced the Mac Pro so early was to get a feel for what the low-end machine should be like, but I'm not very hopefully of a lower-end machine making an appearance any time soon. Most likely we won't get anything till the next generation of Mac Pro, when we might get a discounted current generation as an entry level machine.
