Okay but… obligatory “gVim offers the best of both worlds by offering use of a mouse if you want it”. There are also native ports for Mac OSX and Windows, etc.
Vim, in contrast, is a command-line program, suited for e.g. working with a text file on a remote server that may not even be running an X-windows interface, or maybe the user simply did not bother to connect to it:-).
Okay, we may now proceed with the humorous jesting:-).
Absolutely. Plus the keyboard shortcuts are just outstanding - e.g. shift-M takes you to the middle of the screen - and you can even programmatically do things like make changes to every other line within the range 100-1000 but nowhere else, and even then restrict the changes to only those matching a pattern.
And it is installed on most every machine in the world - even Windows is putting bash onto things these days (I forget if that is still optional, admittedly I haven’t touched Windows in nearly a decade:-P) - and has been since virtually the dawn of computing, certainly long before the modern age. :-D I’ve used ssh on a fucking blackberry and edited files with vim before smartphones existed!
It is, however, notably hard to learn to use, I grant that:-).
