Vim is a nightmare if you don't use it very often. Moving around a text editor with a keyboard feels extremely strange coming from a traditional text editor or IDE.

However, once you get used to it, it's absolutely amazing. You can move as fast as your thoughts, sometimes faster.

I forced myself to use Vim for two weeks after having been a long-time eMacs user (and Notepad++ prior to that). Those two weeks were hell. I felt like a baby learning how to walk.

It felt like second nature a few months later, and any editor that didn't have keybindings felt primitive a few months after that.
