Lion will be available in July for US$29.99 from the Mac Apple store. Here's a quick summary of its features:
New Multi-Touch gestures. These include momentum scrolling, tapping or pinching your fingers to zoom in on a web page or image, and swiping left or right to turn a page or switch between full screen apps. All Mac notebooks ship with Multi-Touch trackpads and desktop Macs can use Apple’s Magic Trackpad.
Full screen apps. iWork and iLife apps, as well as Safari, iTunes, Mail, FaceTime and others, all take advantage of Lion’s system-wide support for full screen apps.
Mission Control combines Exposé, full screen apps, Dashboard and Spaces into one unified experience. With a simple swipe, your desktop zooms out to display your open windows grouped by app, thumbnails of your full screen apps and your Dashboard, and allows you to instantly navigate anywhere with a tap.
The Mac App Store is built into Lion. Apps automatically install directly to Launchpad, and with Lion’s release, the Mac App Store will be able to deliver smaller “delta” app updates and new apps that can take advantage of features like In-App Purchase and Push Notifications.
Redesigned Mail app. The new Conversations feature groups related messages into an easily scrollable timeline, intelligently hiding repeated text so the conversation is easy to follow, and retaining graphics and attachments as they were originally sent. New search feature allows you to refine your search and suggests matches by person, subject and label as you type. Mail includes built-in support for Microsoft Exchange 2010.
Additional new features:
• 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 and continuously saves your documents as you work;
• Versions, which automatically records the history of your document as you create it, and gives you an easy way to browse, revert and even copy and paste from previous versions; and
• AirDrop, which finds nearby Macs and automatically sets up a peer-to-peer wireless connection to make transferring files quick and easy.
