I wonder if I am the only person who feels 'vim shame' (and the closely related 'emacs shame').
'vim shame' - the feeling that you would be a better, more productive coder if only you could master this mysterious editor, but every time you try (about once every couple of years), somewhere between two days and two weeks you find you have drifted back to textmate / sublime editor / eclipse.
For me VIM became main tool when I started to work in multi server environment where all access done through SSH. I could use my most favorite GUI editor Kate to edit files of SSH, but it was less effective due upload/download required.
Do not try to force some tool in your workflow. Instead try it for new tasks/projects and see if it fits naturally. I.e. you should be always aware of other existing technologies, but not forced to use these just because some think it is cool.
Vim isn't compellingly more useful until its ubiquity becomes compellingly useful.
Now I've started to keep my vim config / plugin files in a git repo and deploy them whenever I'm on a new machine. Also as I'm slowly adding new functionality it gets reflected across all environments. I'm hoping this helps this time around.
Disclaimer: I am still conf:ing my .emacs file. :'D
Just to be clear, I'm happy you enjoy your text editor :)
Personally it doesn't matter if you use vim, emacs, Textmate, Sublime, or even Dreamweaver. Whatever you're comfortable with, is what you should use.
I have been a Dreamweaver user since Macromedia made version 4. I then left Windows and went to Ubuntu and started using Gedit... Now I switched to vim... I am by no means a vim god... But I know enough to do what I need to, the rest will come to me with time.
It's not the problem to learn vim, but to unlearn Gimp, Inkscape, etc.
