What's the big deal about "vi", well for one thing it's standard!
You don't find a UNIX system delivered without at least three editors:

	ed - Common campground for computer travellers.
	ex - EXpanded Ed(itor).
	vi - VIsual Ex.

Whenever a program needs to call an editor it often searches for the
environment variable $EDITOR and if defined exec* the editor defined
here. If not defined it will search for a default editor (usually vi -
since it's the most user friendly of the three standard editors).
