Infinite USB Plugs?

Why is it that the Japanese are always on the cutting edge of innovation, yet some of the designs they brew up are so simplistic that you wonder why you hadn't thought of it first? I suppose this is one of those ideas. The good people at Yanko Design dropped another bomb on the head of needless technology, by making the typical USB cord into a pluggable chain of USB cords. It's so simple, I feel stupid. The only thing is that after 4 or 5 plugs, the idea gets a bit cumbersome. I suppose that's why most computers have more than one USB input in the first place. The color coding is a good look too. I hope this gets to the production line soon...
