The point in the article is that the Vim keyboard bindings are most useful. Most editors have an option or plugin for that. That's what I use mainly. For instance I use Visual Studio + Resharper + VsVim ( + AceJump + RelativeLineNumbers) as my main development enviroment. I also use webstorm configured in a similar fashion. Visual Studio and R# understands the code and how to manipulate code far better than anything in the Vim world does, but I use it in combo with Vim keyboard bindings and it becomes incredibly quick to do things.

I don't actually use Vim itself very much ( I still use it for various things, but its not my main editor ). Its nicest attribute is for quick editing tasks it loads quick and can load very large files.
