Here is Apple’s Official Press Release:

Apple Releases Developer Preview of Mac OS X Lion

CUPERTINO, California—February 24, 2011—Apple® today released a developer preview of Mac OS® X Lion, which takes some of the best ideas from iPad™ and brings them back to the Mac® for the eighth major release of the world’s most advanced operating system. Lion features Mission Control, an innovative new view of everything running on your Mac; Launchpad, a new home for all your Mac apps; full screen apps that use the entire Mac display; and new Multi-Touch™ gestures. Lion also includes the Mac App Store?, the best place to discover, install and automatically update Mac apps. The Lion preview is available to Mac Developer Program members through the Mac App Store today, and the final version of Lion will ship to customers this summer.

“The iPad has inspired a new generation of innovative features in Lion,” said Philip Schiller, Apple’s senior vice president of Worldwide Product Marketing. “Developers are going to love Mission Control and Launchpad, and can now start adding great new Lion features like full screen, gestures, Versions and Auto Save to their own apps.”

Mission Control is a powerful, entirely new feature that unifies Exposé®, Dashboard, Spaces®, and full screen apps to give you a bird’s eye view of every app and window running on your Mac. With a simple swipe, your desktop zooms out to display your open windows grouped by app, thumbnails of your full screen apps as well as your Dashboard, and allows you to instantly navigate anywhere with a click.

Launchpad makes it easier than ever to find and launch any app. With a single click, Launchpad displays all your Mac apps in a stunning full screen layout where you can launch, re-order or organize apps into folders. You can also arrange apps into multiple pages and swipe between them.

Lion brings the full screen experience that iPad users love to the Mac. With one click, your application window goes full screen, taking advantage of your Mac’s brilliant display. You can swipe from one full screen window to another and even back to your Desktop or Dashboard.

New Multi-Touch gestures and fluid animations give you a natural and intuitive way to interact with your Mac. New gestures include pinching your fingers to zoom in on a web page or image, swiping left or right to turn a page or switch between full screen apps and swiping up to enter Mission Control.

Lion also includes the Mac App Store, where you can find great new apps, buy them with your iTunes® account, and download and install them in just one step. Apps purchased from the Mac App Store are installed directly into Launchpad.

Additional features in Lion include:

  • a new version of Mail, with an elegant, widescreen layout inspired by the iPad; Conversations, which automatically groups related messages into one easy to read timeline; more powerful search; and support for Microsoft Exchange 2010;
  • AirDrop, a remarkably simple way to copy files wirelessly from one Mac to another with no setup;
  • Versions, which automatically saves successive versions of your document as you create it, and gives you an easy way to browse, edit and even revert to previous versions;
  • Resume, which conveniently brings your apps back exactly how you left them when you restart your Mac or quit and relaunch an app;
  • Auto Save, which automatically saves your documents as you work;
  • the all new FileVault, that provides high performance full disk encryption for local and external drives, and the ability to wipe data from your Mac instantaneously; and
  • Mac OS X Lion Server, which makes setting up a server easier than ever and adds support for managing Mac OS X Lion, iPhone®, iPad and iPod touch® devices.

Apple designs Macs, the best personal computers in the world, along with OS X, iLife, iWork, and professional software. Apple leads the digital music revolution with its iPods and iTunes online store. Apple is reinventing the mobile phone with its revolutionary iPhone and App Store, and has recently introduced its magical iPad which is defining the future of mobile media and computing devices

      I’d like to know the answer to that question as well. Plan on installing it on my MacBook Air (late 2010) w/Windows 7 Ultimate via Boot Camp. Has anyone done this?

        I have installed Windows 7 Professional through BootCamp, works perfectly. New BootCamp 4.0 is in Lion, and it’s great. Make sure to download the WindowsSupport drivers from BootCamp and burn them to a CD. Good Luck!

      It’s saying the same for me, I just tried to see if a new redeem code was posted /since I had a problem downloading the file and now it won’t download at all.

    Thank you so much for Lion. I’m already loving it. I also noticed that iOS was listed and would it be possible for me to be listed for 4.3 also? When I clicked on it I was given an error message.
