Spots before the eyes

I guess I wasn’t paying attention to the Leopard previews earlier in the year, because OS X just blew my mind. I was editing an e-mail message, and decided to idly click on Time Machine to see what it was doing. Instead of the Finder going into Time Machine mode, my e-mail went into time machine mode. I clicked the back arrow a couple of times, and there was what my e-mail inbox looked like 2 days ago, complete with since deleted messages.
