Some of these interesting new features include; the Mac App Store, Launchpad, full-screen apps, Mission Control, gestures and animations, document-based app features such as 'auto save', 'versions' and 'resume', as well as the new Mail 5, AirDrop, the FileVualt and Lion Server.
Also Apple is now providing a download of the Mac OS X Lion Developer Preview to all those enrolled in the Mac Developer Program so that Mac developers can get all their apps ready to be in the Mac App Store when Lion ships in the summer. This is however only available to those enrolled into the program, not everyone who has registered as an Apple Developer using their free tools.
Get more information about the Mac Developer Program to program for the Mac at developer.apple.com.
