Keyboards and mice are nice because they require relatively small, efficient movements. The only thing that would improve mice is to make them disappear. Replace the physical puck with some kind of image capture or accurate position sensing system that tracks all fingers for pressure and position, and you'll be able to make even smaller movements on any surface while keeping your wrist rested. Keyboards need some physical travel, and modern designs have reduced that as far as it can go. Some people prefer Cherry-type clacker keyboards, some people prefer Apple-style micromovements, and some prefer something in between. Pick whatever works for you. There are choices. I suspect there are flat touch keyboards in Apple and MS labs somewhere, and I also suspect they'll stay there. It's a perennial idea, but it's not happening until a technology is invented that can emulate key travel in any location(s) on a lightweight programmable display surface. That would be amazing - like the app-dependent touch bar, but both comfortable and useful. Gestural interfaces look sexy in movies, but I really don't believe days of waving your hands and arms around and talking are going to be easier on your body than a modern keyboard+mouse mix.
