Well, ain't that brilliant. Why did nobody think of this earlier?
^Funny story....
A few years ago, when I was still a teenager, I had this same idea (well, it was for a powerbar, but the same concept). Strangely enough, just a few weeks later, Engadget reported that a company had filed a patent on it. They also said the same thing: "Why didn't anyone think of this earlier?"... to which I can respond, "I did!"
So anyway, while this outlet seems to be a new application of an existing idea, I'd still love to have one.
Such a smart idea!!!
