I can see where you're coming from when it comes to comfort with the mouse, though I don't think you should emphasize it too much if you've never experienced some kind of "never leave the keyboard" system that you're fluent in. It may or may not be faster than a mouse, but it's faaaaar more precise and for me feels very satisfying in a tactile sense.

Though in my experience, once you go all in, you start trying to get it to work on everything; in my case that means vim keybindings for everything, including web browser, and it can be a bit jarring to give it up when you use someone else's computer.
