But you understand why people plug a mouse into their laptop instead of using the touchpad, why they use Ctrl-C instead of copying with the mouse, why they autocomplete code in the IDE using keyboard shortcuts instead of clicking through menus and why they sometimes prefer a physical keyboard on their iPad instead of typing with two fingers on a non-tactile screen?
Sometimes it's not about being more productive but about turning the stuff you do every day from a chore riddled with tiny annoyances into a more enjoyable, coherent experience. With Vim I don't have to worry about annoying "smart" features, popups with suggestions I never asked for, no need to switch between mouse and keyboard all the time for little things like selecting some text or opening a file, and at the same time it has the most flexible system for custom keyboard shortcuts I have seen to date.
