There is a lot of new functionality in OS X Lion – there’s no denying it.
Having only played with it for a couple of hours so far by far the coolest thing is the new gestures.
Do yourself favour and look at the instructions that are now available in System Preferences. Much like previous versions this little tool demonstrates all the gestures available with in built trackpads or Apple’s external trackpads.
Spend a few moments and get aquatinted with the new functionality.
