I disagree with #2, now at least. First rule of emacs: don't quit. Or, more specifically, don't shut it down. I used to do this, but a few months ago I managed to really screw up a file I was working on, but didn't notice the problem until after I had saved it. And because I hadn't closed that emacs session for over a week, I couldn't even revert to a backup without losing a week's worth of work (emacs normally only creates a backup file when it closes). So for the last few months I close every session every day when I quit for the night.
