When the lion roars — it does it so that the entire jungle hears. At Apple's "Back to Mac" event, Steve Jobs unveiled the next major update for the Mac: OS X 10.7 Lion. Here's a list of some of the features that Jobs unveiled today.

1. OS X Meets iOS

Multi-touch gestures is coming to the Mac OS X. Steve Jobs says that touch surfaces can't be vertical — they must be horizontal or else fatigue occurs. The trackpad will remain the focus for multi-touch gestures.

2. Mac App Store

One click downloads and free and paid apps — all in one place. Automatic installation auto app updates will happen just like on iOS devices. The Mac App Store is not exclusive to OS X Lion, but will available on Snow Leopard in 90 days.

3. Mission Control

Expose, full screen apps, Dashboard and Spaces will now be unified. An Expose-like view shows which apps are open with their respective open windows.

4. Launchpad

With just a click you can now launch apps. You can organize apps in pages and folders exactly the same way you can on iOS. Just drag and drop.

5. Full screen Apps

Applications can now be opened in full screen. There is no need to leave full screen when switching apps. A gesture swipe will let you move between open apps.

Availability

Mac OS X 10.7 Lion is on track for a Summer of 2011 release.
