Yeah, that's what I thought too, at first. But that's assuming it's legitimate, and not a scam. I did a quick search on Google, and couldn't find out much. Most of the information about it is released by the company itself. I didn't find anything about a prototype, but didn't see anything especially suspicious either.
That's why I was wondering if their claims were very realistic or likely. Technology changes so quickly, and I don't keep up with it enough. I know that some of the folks who post here know way more about these technologies than I do, and are in a better position than I to make a judgment about the claims of the cube.
Of course, I want it to believe it's true...

But therein lies the danger
