David Pogue recently wrote an article that looks at the similarities between a revolutionary multi-touch interface designed by Jeff Han, and the multi-touch interface that Apple will be using in their iPhone.
David contacted Jeff and was surprised to find out that Jeff wasn't angry about what Apple was doing. In fact, he said that he wasn't allowed to discuss the issue. Could this mean that he is involved in a possible collaboration with Apple? If so, this is going to be a huge technological gain for Apple over other companies trying to revolutionize computer interfaces.
