It's like the DNA of the Wii is getting injected into mobile phones... A few upcoming smartphones are using this to conserve power- switching off the screen when it senses proximity to the side of one's head. The true ease-of-use app for this, as you say, is allowing the user to scroll images and sites larger than two square inches.

I also like that Kim Possible/Aeon Flux cartoony pic. It also has elements of Men in Black: "Look into the red light, please..."
