Today, Facebook Home is live on the Google Play store. Introduced by the social network last week, Home, is a new mobile system focused on the social experience. Like the social network's updated News Feed, Facebook's new not-quite-an-app, not-quite-an-operating-system Android experience, takes on a more visual design that puts content first (like being in full-screen mode on your browser).

The new mobile look is "deeply personal" and designed to help smartphone users stay connected with friends and family. Facebook Home is essentially a set of Facebook apps that takes over your phone. It feels like system software, not just an app that's running on your mobile device.

Facebook Home is compatible with the HTC One X, Samsung Galaxy S III, Samsung Galaxy Note II, and the yet-to-be-released HTC One, and Samsung Galaxy S4. Before you download Facebook's new social software, take a look at Facebook Home's standout features and let us know what you think of the social network's new way to share and connect on mobile.

Facebook Home will also be available on HTC First ($100) on AT&T, the first Facebook Home-optimized phone.

The part-time laptop, part-time tablet devices running on Intel's new lower-power computer chips will do double duty for up to 13 hours — the biggest battery life gain in the company's history.

Read on for more about what Intel's CES event told us about the future of mobile computing, and see the new high-performance hybrids available this year for yourself.
