You can take away my save button, as long as you make it easy to discard my current work as well. The version control like systems we have today are ok (Time Machine, dropbox, Windows previous versions), but not ideal. If I'm using a word processor that is automatically saving, why should I have to then explore my hard drive to find the file and examine previous versions? The app I am using needs to present this interface (even if it is ultimately supplied by the OS, like save dialogues).
