Apple just announced a new feature to OS X Mountain Lion called Power Nap. It syncs your computer's email, keeps track of calendars, syncs to Time Capsule, and downloads App Store and system software updates—all while your computer's asleep.

This is basically Intel's Smart Connect, just for Apple's stuff, but it's one of the cooler this-gen features out there, so this is great news.
