In case of the browser, I've augmented it with the Vimium add-on. I've gotten so used to touch-typing that I'm annoyed when I have to reach for the mouse, even despite the inherent delay for reading Vimium's label on a link. That's why I want a touchpad in quick reach. And also for the two-finger scroll with its analog sensitivity.

This keyboard-reliance has led me to another observation, that web devs don't test keyboard scroll on their sites.
