Here's the an unofficial version of the official OS X 10.8 Mountain Lion preview video, showcasing some of the 100 new features Apple plans to include in the upcoming version of their desktop OS.

With Mountain Lion, Apple is moving even further into merging the experience between the iPad and the desktop, integrating features like Messages, Notification Center, Reminders and more.

Apple's version isn't embeddable at the moment so we're including one from YouTube. We'll update with an official version if/when Apple releases it.
