Interesting that that the intro video also seems to be a subtle demonstration of new natural language commands. Kind of a clever way of minimizing "Siri" by packaging it into something much bigger. I'm curious how some of the actions are initiated - the video implies that visual recognition/location awareness/voice commands initiate the search, but I wonder if a button is also pressed.
