Also less simple revision history. For some long lived documents I keep a "release branch" and make branches for playing around. If a direction or section isn't fruitful I can leave it on a branch without fear of losing "something good", and go back to mainline. I can also tag shared/published versions easily. Oh and push a backup to another machine easily or automatically.
