I have been using terminal almost exclusively for about a decade or more. But, when I started I just decided to do it. And that meant that every time I wanted to do something, it would take me forever because I would have to look it up. Eventually, I got faster and faster and now anything I want to do with a gui, I can almost certainly do faster with terminal.
The issue I find with the surface is that it just isn’t lapable. Using it on my lap is nearly impossible. Good on a desk though.
