I love Lion's idea of consumer-grade version control, which Apple calls Auto Save and Versions. I'm just not particularly happy with its GUI. That's because it relies on a new vocabulary of menu choices and on users understanding what's going on under the hood.
Take the save options for example. You can "save a version," "duplicate," etc. These are very good tasks to do. My question though is if these are the right tasks and the right names for the typical Lion user.
If you go out and ask a bunch of people what the "save a version" menu item means, you're going to get a lot of answers, many of which don't agree. In Lion, this menu option creates a new revision point for your doc
