For instance, notepad is default on windows, and I'll use that when needed on vanilla windows machines, but for the 99% of my editor needs I install and customize a number of enviroments (including Vim). I don't mind whether it's installed by default or not.
I know this is an issue where I work. We have 40 thousand plus servers, and we aren't going to have everyone install their editor of choice on all those machines. If I have an issue I need to check on a server that requires some text editing, I have to use one of the default editors.
There is actually this neat hack you can use(if you use VIM) with rsync.

I know it's kind of Hacky, but the performance improvement is worth it IMO.
I normally just use TRAMP. For those who've not used it, it's an incredible little emacs package which gives one a very Plan-9-esque feeling, in the sense that all the different systems one connects to feel like one whole.
As an example, when one is editing a remote file shell-command runs commands on the remote system, and of course find-file and friends work exactly like normal — only looking at files on the remote system.
I glanced over much of the presentation, and none of it was about the editor itself as a user would see it. I'm impressed and glad for the technical investment, but to be even a consideration for a replacement, I need a focus on how it's supposed to be an improvement, not just a substitute, for vim.
I have tried tons of editors, and I always come back to vim. Heck, I have even moved my .vimrc to be the simplest possible with the smallest number of plugins.
