vim

My personal Vim configuration

####What is Vim? Vim is a text editor that improves on the vi editor that is distributed with most UNIX computers.

####Why use Vim?

Improves Efficiency (eventually)
- Stay in the command line
  - Don't need to switch between applications
- Forces you to use keyboard shortcuts
  - Doesn't use a mouse
- Easier / quicker editing on servers
  - Linux servers use vi by default which has the same general commands
  - Don't need FTP, etc to take down locally and edit with your local text editor
Customizable
- Numerous plugins
- Pick your own settings
Well Supported
- Open Source
- Been around since 1991 (public release)
Lightweight
- Quick startup
- Not a resource hog

This Post says it better.
