10.7 coming next summer
Apple has announced the next version of Mac OS X, which continues the feline theme with the name "Lion." Version 10.7 brings several features that were originally pioneered for iOS on the iPhone, iPod touch and iPad. Users will be able to take advantage of multi-touch gestures, an app store, app home screens, and fullscreen layouts.
The Mac App Store is based on its iOS counterpart, offering developers the same 70/30 revenue split. The portal has been described as "not the only place, but the best place to discover apps." Users will be able to download apps with a single click, with automatic installation and app updates.
Lion will also integrate a new Mission Control feature, which unifies a variety of content using Expose-style windows. The interface provides a shortcut to the Dashboard, while apps are grouped into clusters. Users can control everything using gestures.
A new Launchpad icon will transition from open windows to a fullscreen display of all the apps on a Mac. Users can swipe to see multiple pages, or arrange apps into iOS-style folders. Content downloaded from the App Store is automatically added to the Launchpad.
Apple expects Lion to be ready by summer 2011, but the Mac App Store will be added to Snow Leopard sometime within the next 90 days.
