"Yes. Can you think of some examples? I can't think of a single I'd like to do on a desktop computer that wouldn't be easier and more-precise with a mouse." Currently we have mostly just mouse+keyboard, so it's pretty much expected that majority of present applications would be optimized to work best with these inputs. Once we will have more expressive inputs, new types of applications will start to pop up. For example, I often work with 3d. For such applications, mouse + keyboard controls feel very clunky. Even simple tasks like setting up cameras or placing objects in the scene are pain. It would be much more natural to manipulate 3d objects using gestures in 3d space.
