Thats interesting. Im using GUI Windows OS, but im very heavy keyboard user, utilizing shortcuts and alt+tab for windows switching. I barely even use start
or desktop to start most common apps I use. I wrote myself QuickRun tool that is activated by Win+Q, and I type what I want to run. Usually its just 2-3 first letters of alias name, like bash and autocompletion kicks in. Mouse is used mostly to position windows sometimes. Keyboard is just much faster..
