Briefly, Vim is a successor of vi, in lower case, written in 1976 as a Linux editor. If you do any serious work in Linux, you really need to equip yourself with that tool.
This documentation by IBM is a thorough discussion of acquiring and using Vim, and the following list – a partial list – of platforms to which it has been ported:
- Amiga
- AIX
- BSD
- Cygwin
- IBM OS/2®
- Linux
- Apple Mac OS and Mac OS X
- Microsoft® MS-DOS®
- Microsoft Windows® 95 though Windows Vista®
- Microsoft Windows CE

The references (IBM’s documentation is very thorough) include the AIX wiki article, vim.org, and podcasts featuring IBM experts.
