Looks pretty good actually, but maybe not quite there for the carPC crowd. For instance, I see no reference to a sound card, and certainly no input or output jacks. "Maybe" audio is available over HDMI, but you'd still need some way to break it out and get it to your audio amps and speakers. And with a single msata connection, you're looking at either spending a fair chuck of money for a large msata SSD, or going with USB (or Thunderbolt) attached storage. Probably a USB sound card as well. So while the performance and form factor is pretty much right on the money, you may wind up with a lot of peripherals hanging off the USB bus.
Also notice there doesn't appear to be an on/off switch, so it may be difficult to use it in an automotive environment. It draws 10wts at idle, so it WILL drain your battery if you wire it to be "On" all the time.
Jeez, I sound like a real Debbie Downer, don't I? I REALLY like this idea and size, and hope they go all in (as Anandtech) suggested and build out a complete ecosystem for these boxes. I may pick one up early next year just to see what it can do.
