- I don't have to save my documents. It's done automatically.
- Collaborating is really very easy. Multiple users can edit the same document simultaneously. To let someone view my document, all I have to give them is a link. Whenever I update the document, I don't have to send the new version to them; they always get the latest document.
- I don't have to carry around my files. It's always there in Google servers (with enough backups :-).
Google Docs is in its infancy now. After a few years, I guess, I won't miss Microsoft Word!
PS: I used Google Docs to write this post.
