too bad they don't have a faq on their website.
From the looks of things, the device gets powered via a powered USB hub (which is $10-20 additionally). Then add a USB keyboard and mouse, and a TV, and you're set!
They also did not mention anything about mass production, nor price.
I think it looks like a prototype right now, still in the developing phase. One of the things it probably needs is a plastic jacket. And from the looks of things, it's going to become bigger than a USB stick, since it has more than 2 ports (it also has an SD cardslot, and webcam/other device port).
