Sorry — I never know when to assume a large amount of knowledge or a small amount of knowledge. The worst for me is "ctrl-w" to delete a word backward in Insert mode, and to delete a tab in the web browser :) Vim is in my muscle memory and it's faster for me, so that's why I use it. It might be faster for you and it might not be faster for you, and if you don't need the portability for POSIX machines it's probably not worth the time.

CTRL+W messes me up sometimes. when i'm in split screen mode with two panes i'll often tap CTRL+W twice to switch panes. very confusing when you forget to exit insert mode.

Yes! I use mutt + vim. Composing emails in a textarea is a terrible experience by comparison. (Respect to emacs mail mode users, that’s a great option too.)

I also use w3m for browsing technical stuff, and use tmux for copy & paste into vim.
