I don't get it.  This does just seem to me to be Apple reinventing the shuttle.  Rossj, I'm not sure what you were trying to say, because the shuttle is another company using Intel chips to build a box in the form factor of this "mac mini".  The PC world has had ITX mobos for some time now.  And you can build machines with much smaller form factors than this "mini mac".  For instance, check out the Windows XP Box in a "Windows XP Box":  http://www.mini-itx.com/projects/windowsxpbox/.

Now, if the deal is that it's an affordable Mac... well, it makes me a little interested, but the fact that it's so "lite" in it's power means I'm only a *little* interested.
