New features include:
-"Mission Control" which gives you a complete overview of your computer, with all virtual desktops and windows all visible all at once.
-"Launchpad" which is like the view on an iPad or iPhone, it views all the apps installed on the computer and allows you to create folders and move stuff around in the fashion of iOS.
-"Mac App Store" I can just see problems beginning to rise with this, anyways, the Mac now has a brand new Mac App Store that will be similar to that on iPad and iPhone except you buy apps for the Mac.
-"Full Screen Apps" programs and apps will now be able to run full-screen
-"AutoSave" programs and apps will now auto-save
-"FaceTime" Macs are now allowed to FaceTime with iPhones, iPod Touches and other Macs.
And "heaps" more features according to Apple.
