ExKate - Coolest thing on 4 wheels, evar

So, the reason I've been thinking about all the activity I do is that I'm completely enamored by this amazing contraption of fun, back to the future style. Wireless remote controlled electronic skateboards, who would have thought? Hidden behind an awesome toy is actually some interesting technology. It boasts: "It is the first time in the history of mankind where the human body is used as an antenna between a transmitter and receiver." Basically, you hold the control in your hand, and it uses the body as the link between controller and skateboard, so when you fall off, it actually stops. The thing is pretty heavy with batteries, but it gets a 10 mile radius, and speeds up to 22 mph. I dug around in the FAQ, and they mention regenerative braking, which is a fantastic idea, I'd love to see more stats on that. It also has a really awesome turning radius.
Wow, I would love to have one of these. I do wake board, and the control scheme is pretty similar, toe/heel flexion to steer. It would really help my balance. That's a good reason to buy it, right?
