"I think pinch to zoom is pretty innovative and someone should get credit for coming up with that idea." Pinch to zoom is there since multitouch technology in the 1980s. Once you start experimenting with multitouch, pinch to zoom is obvious in 5 min. It was very common in the industry. I was using it for transforming(amplifying an rotating) and moving vertex of an "elastic"(tesselated) vector shape in the early 2000s, late 90s, and we were not the first to do it with wacom multitouch. The same with "bouncing effect" that is just adding elasticity force to elements. The problem is that someone could take what already exist in the desktop and patent it "on a mobile device", or "in the browser" and have a monopoly for 20 years. This is as simple as the US gov selling monopolies to the highest bidder.
