What's the point, though?
You still have to rely on POSIX and / or GNU tools in most scenarios, and if already knowing / using those, then why bother to switch to anything else?

Getting to know and use a standard setup makes you efficient in that situations, that is also the reason why I learned to use vim (since vim or at least vi you can take for granted there is on every system).
The only concession that I make is the shell, since zsh is much more convenient to use than bash, even if every time I use a system with bash I of course write some code that works in zsh and have to remember that in bash you can't do it. That is annoying, but to me it's worth it to use a better shell, not worth probably for an `ls` clone.
Coworker machines are whole different issue though - most of them have American keyboards (I do not), most of them do not use editors with vim bindings etc.
