> the debate was "keyboard vs touchpad".

I didn’t mean for it to be that exclusively. I tried to say that keyboards are the best text input device, but gaming mice and controllers are the best gaming input device, graphics tablets are the best graphics input device, and video editing input devices like the ones I linked in my original comment are probably best for video editing (while trackpads are at best decent scrolling/browsing devices, but IMHO I personally prefer keyboard scrolling like in the terminal pager less, the PDF and other document viewer Zathura, and vi-inspired browsers/browser plugins like luakit, qutebrowser, and Pentadactyl).
