I'm liking the app resume feature more then I thought I would. At first, it irritated me that old document windows would reopen when I open a program. Now that I'm getting into the habit of closing windows and documents when I'm done, vs closing the app to do so, the feature is coming in handy in other areas. Just updated my Mini to 10.7.1, and after rebooting, my desktop came back exactly as I left it.

Shutting down is also more pleasant, since I'm not bombarded with save windows from notes I tend to make in a text editor. It's just saved automatically and will restore the way I left it.
