I think I get what venam means here: switching tools takes you away from your original goal. When I want to take notes, I don't wanna bother with learning how to save (:w ? c-x c-s ? c-w ?), so if all editors had a common way to do it, that'd be easier to switch tools.

I don't particularly agree with that though, as this would prevent having good idioms like vi's mosal edition, which is just so different from traditional edition. It's aboit choice after all, so the best way to lessen ties woth a machine is to provide multiple alternatives. For example, ubuntu has both vi and nano by default. Openbsd integrated mg specially for that: providesimple alternatives on the base system.

I personally think that to lessen the burden of "learning tools", the best solution is to provide a common intrrface to them, so you are not surprised when learning the tool. OpenBSD does it right, as all the configuration format for their tools are STRICTLY the same. Take nsd or httpd, both will use the same keywords to listen on an interface. They also all have great manpages with a good documentation, organized in the same way.
If their was a common ground for all unix tools, that would be much easier to swap systems, I guarantee it !

Now until we get that, I'll keep installing stuff statically to ~/.local so I can easily "migrate" from one system to another ☺
