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:-).
