I disagree. What Nokia is solving here is true buttonless navigation. No one else is using swiping in that way. However everyone is trying to go buttonless. Android has done it in the easiest way, replacing hardware with software buttons and calling them not-buttons. It has been rumored that iOS will go buttonless too, but who knows how. WebOS is the only that has kind of done this. You can navigate WebOS without buttons but it still has a "button" in the gesture area that most people use anyways. Swipe is the first time someone has been able to make the OS buttonless in a way that doesn't feel tacked on. Calling that revolutionary is hyperbole, but it is an important UI development for where we are inevitably going.
