I wish I could use vim or emacs. I don't know if I'm stupid or something but all of the key bindings, everything you have to remember, it just doesn't make sense to me. I wish there was something like nano + plugins. If I had that I could implement most of what I need (other then auto-completion for a crap load of languages).
Try out Vim Adventures to get some basic commands down. Then find Vim emulation for your editor of choice. Leave it in insert mode as much as you need at first. Slowly you'll start using more Vim commands. In a while you'll wonder how you ever edited without it.
I assume the non-free bits continue in suit, although sticker shock prevented my finding out. For someone benefiting beyond entertainment, it's likely worth it. As a long time vim user I had trouble justifying it.
