Mountain Lion’s Power Nap will keep your Mac updated and backed up while it sleeps

One cool new feature you can expect in OS X 10.8 Mountain Lion is Power Nap. Similar to Intel Smart Connect for Windows, Power Nap allows your Mac to keep itself updated and backed up while it sleeps. Your Mac email and calendars will stay updated, your Time Capsule backup will be performed, and even your system updates and Mac App Store updates will 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. One odd tidbit about this feature is that Power Nap only works with Macs that use flash SSD storage. So if you are rocking an HDD, you're out of luck on this one. Power Nap is one of many new features you can expect from Mountain Lion which will launch in July for $19.99.
