Not the OP, but a lot of people (myself included) have minimal mouse interaction even when they use X-windows. For example, I use a tiling window manager and only interact with it through the keyboard. I use urxvt as my terminal emulator and while I suspect it has some kind of mouse support I have no idea what it is because I have never used it. I have my web browser set up so that as much as possible everything is controllable through the keyboard. I move all my windows around, resize, hide, focus with the keyboard. I don't have any menu bars at all. All of the apps I use I have hidden the menu bars if I can because I don't use them.

So even with GUI apps, I tend not to use the GUI. I don't think I'm alone. Virtually everything I run is either a terminal app to begin with or can run from the terminal. I have tmux set up to work almost exactly like my X window manager, so if I don't run X I barely notice. I'm just as productive without X window as I am with it except for a very few things: browser, gimp, a few games... Honestly I can't think of very much.

It's great that some people like GUIs. I used to use them a lot, but have since found that I'm happier without them. The keyboard is not really a discoverable UI device most of the time, but it can be ridiculously efficient once you learn how to use it. I also have very poor eyesight, so that probably predisposes me to using interfaces where I don't need to use my vision.
