Yeah I like the vid. However what would make the interface much better, and the reason for it happening, would be for complete control and hands-free ability - having to tap something on the screen defeats the purpose, for instance if you're driving or cooking or in the bathroom or something and you can't/don't want to touch the phone, you should be able to control it completely by voice (like the Knowledge Navigator, or current and actually in use Kinect where you simply say "Xbox ..." followed by the command). If your hands are dirty while cooking and you don't want olive oil or flower do get on/in your iOS device, and you need more information you could say "iPad, next page" or "iPad, what is the next step in the cooking process" or if you get a text you can say "iPhone, read text" and then "iPhone ignore" or "iPhone reply with: ..." and then say the message you want the iPhone to type and send to them while you're still stirring or transferring or coating your food.
