Longtime Mac Pro user here, currently using a (nearly) maxed out 5,1. I took a ho-hum approach to this WWDC because I'm really just interested in the mMP apparently coming out next year. I have to admit, though, that I am a bit attracted by this extremely powerful all-in-one. I don't mind the idea of enclosed external storage.
For what you're getting, the price actually doesn't seem horrible. Like many others mentioned, however, I'm very curious to see how the heat dissipation works out. Ever since my 2.6 GHz quad core i7 Mac mini tried to burn a hole in my desk while under load, I've been skeptical of putting powerful equipment in a small space. Speaking of which, for the folks out there wishing for the 4-core mini back, I have one, and the extra 2 cores are not all that useful. The reason for this is that if you actually have a program that uses them all (FCPX rendering in my case), the chip heats up, clocks down, and runs slow as molasses.
