how big is the power supply though?
That's always a problem with small boards. Sure, you can shrink the PC board down, but what about every other thing that connects to it? I think there comes a point of diminishing returns when this, and the added costs are considered. Some applications can benefit greatly from a tiny MB and externalized power / peripherals (like a Laptop uses), But if you can physically fit a mini-ITX into your project and it's cheaper and it has better performance, and., and, and then one would be silly not to go the more practical, albeit larger, route.
Tiny PC boards almost always equal higher cost, lower performance, and often times less practicality. And forget adding special video cards or other non-USB compatible upgrades.
I'll be interested when they cost < $150 each and include the external power supply. Of course this will probably not happen as, regardless of what VIA states about gearing toward consumers, this is an industrial geared product That market is always willing to pay more for less as long as the footprint is small and the markets drive the pricing.
Still, the "geeky gadget" appeal is undeniable
