Mac OS X Lion is Apples eighth major release of Mac OS X, Apple's s desktop and server operating system for Macintosh computers. A preview of Lion was publicly unveiled at Apple's "Back to the Mac" event on October 20, 2010. It will bring many developments made in Apple's iOS, such as an easily-navigable display of installed applications, to the Mac, and will include support for the Mac App Store, as introduced in Mac OS X Snow Leopard version 10.6.6.

iOS 5 is the next version of Apple's mobile operating system. iCloud is expected to be Apples new internet storage service offering.

In addition to seeing the latest Apple's products, fans will be happy to hear that CEO Steve Jobs will take center stage by delivering the keynote address. Jobs is currently on his third medical leave of absence since 2004 when he left to battle a rare form of cancer.
