The reason I chose Vim over Emacs is simply because of the fact that it's available literally EVERYWHERE. I've honestly never seen a UNIX system which doesn't have Vi or Vim installed by default. Emacs is more hit and miss.
You should read the article. Vim does run everywhere, including inside Emacs. You don't "choose vim over Emacs," you choose vim, and optionally Emacs if you want to use Emacs in whatever context. evil-mode is a great vim; using that won't stop a vim user from using native C vim instead of emacs lisp vim when logged into a remote system
I think you have to see someone who has used it for a while (or use it for a while yourself) to understand.
To me nano is just a basic text editor (open, edit, save). Vim is a way to 'jack in' and be able to manipulate text with my mind. I don't 'think' anout how to accomplish something, I just think about what I want done and my hands just do it.
This comes from the modal nature of the editor and text objects, mostly, but there are so many other little things (like macros, ex commands, filters) that you pick up over time that all add up to a great text manipulation toolkit.
Are you being serious? Vim offers so much more advanced features. But if you don't have a use for those advanced features of Vim Nano is probably more than enough for your use case. I just find Vim more enjoyable to use even for simple tasks since the commands are already in my brain and I really prefer the modality.
In the Linux world, sure. The only reason why I've seen nano (rather, pico) on many non-Linux systems was because pine was installed, and that was only on multi-user systems.
On a personal level, I am not going to disagree with you. I configured Pine to use vi (or whatever vi variant shipped with AIX). I also seem to recall configuring lynx to use vi to edit forms (which made using web based forums bearable).
That said, editors are a personal thing. Pico was certainly a better choice for most people. In most cases, their needs are basic. Pico also displayed the relevant keyboard shortcuts on the bottom of the screen. Why would they want to complicate things, and vi would complicate things for people who did not have a need for a text editor outside of composing emails.
