Multi-user editing can be really great sometimes. That's something that the desktop apps don't have or don't use effectively. Behind-the-scenes version control is in Google Docs, so I'd expect it to be in their presentation app, too. That can be really handy, as well, and while you can do versioning decently in Powerpoint, I don't think may people use it.
