Multi-Touch Gestures :
Multi-Touch gestures transform the way you interact with your Mac, making all you do more intuitive and direct. Now an even richer Multi-Touch experience comes to OS X Lion. Enjoy more fluid and realistic gesture responses, including rubber-band scrolling, page and image zoom, and full-screen swiping.
Full-Screen Apps :
OS X Lion offers systemwide support for gorgeous, full-screen apps that use every inch of your Mac display. You can have multiple full-screen apps open at once — along with multiple standard-size apps. And it’s easy to switch between full-screen and desktop views
Mission Control :
Mission Control brings together full-screen apps, Dashboard, Exposé, and Spaces in one new feature that gives you a bird’s-eye view of everything on your system. With a single swipe on the trackpad, your desktop zooms out to Mission Control. Think of it as the hub of your system: View everything and go anywhere with just a click.
Launchpad gives you instant access to all the apps on your Mac. Just click the Launchpad icon in your Dock. Your open windows fade away, replaced by a display of all your apps. Arrange your apps any way you want, group them together in folders, or delete them from your Mac with ease. And when you download an app from the Mac App Store, it automatically appears in Launchpad, ready to blast off
Now apps you close will reopen right where you left off, so you never have to start from scratch again. And when you install software updates, you no longer need to save your work, close your apps, and spend valuable time setting everything up again. With Resume, you can restart your Mac and return to what you were doing — with all your apps in the places where you left them
OS X Lion introduces a whole new take on email. Mail puts your entire display to work with a gorgeous widescreen view featuring a full-height message and a message list that includes snippets. Conversations presents messages from the same thread in an elegant timeline showing each communication as it was sent while hiding redundant text. Mail also features search suggestions and search tokens, which help you find the messages you’re looking for fast. And a new favorites bar gives you easy access to the folders you use most often
