I don't really see this as a replacement for touch typing. It's telling that there's a keyboard and mouse to the side of the computer during the video. Instead, I see the sprout as a way to replace more specialized hardware controllers with software. Many applications, such as DJ software and vector graphics software, can benefit from integration with input devices. But this leaves manufacturers with a choice: 1. Force users to buy the controller, with the software (which adds cost, and may dissuade many potential buyers, as well as limit customers to your controller). 2. Use existing input hardware (keyboard/mouse) (which leads to an inferior user experience). 3. Offload this choice onto the user, who can start with the existing input hardware and later switch to the specialized controllers. However, this requires supporting two systems, and sometimes the poor user experience from using the default controllers will prevent potential users from using the software with the specialized controllers. Sprout sidesteps this problem completely by allowing software definition of controllers. I think the big problem HP will run into is that if other manufacturers don't create similar products, HP will have a difficult time getting software developers to develop for the Sprout because it would lock them into HPs platform.
