But the interfaces were always an abstraction, your mind had to learn a different way to interact with something regardless. The tactile feedback is somewhat overstated IMO, you know that what you're feeling and what you're doing aren't directly related, unlike manipulating a Rubik's cube or something. It's good to have that, it helps with an interface, but it doesn't have to be the same as a keyboard just like a keyboard doesn't have to be the same as arranging letter blocks on a table. Touching what you're trying to manipulate, such as on a touchscreen, is more intuitive, but that's what makes it less powerful for complex tasks; you want your abstract interface to enable you to manipulate more than just what you're seeing in front of you, a keyboard does that, a touch screen does not.
