OSX Lion's fullscreen mode emphatically "is" unique. I haven't seen any other desktop OS that has a system-wide fullscreen (not maximize) button and nobody else is even in the game when it comes to bringing multitouch gestures to the desktop. The gestures are important - the entire point of Lion's fullscreen idiom is to bring the intuitiveness and immersion of post-pc apps to the desktop.
