[citation][nom]robochump[/nom]Good catch. It is not uncommon for an idea to appear from multiple sources at nearly the same time. Its whoever can get the patent 1st that wins...lol. In this case I can assume Apple came up with the concept first and will hopefully work with or allow other institutions/companies to develop the hardware.[/citation]
Obviously, you have not been following the news lately. Either that, or you're very naive to think that Apple would ever "work with or allow other companies blah, blah".
Besides, that's not the case here. Not only the concept, but also the prototype exists (and has been here for about a year already, if not longer). But hey, even if someone showed you the working device, you would still believe it was Apple that came up with it first, because that's what living inside Apple's bubble means.
