How to revert input behavior changes in OS X Lion
OS X Lion comes with a number of new and altered features, some of which, like Mission Control and full-screen options, can be avoided if you don't find them useful. However, Apple has also included a couple of alterations that cannot be quickly avoided and that new users might find a bit frustrating.
The first of these is the default scroll direction on Apple's multitouch trackpads. In prior versions of OS X the scroll direction mirrored that of scroll wheels on mice, which when rolled toward the user cause the page to scroll down. The trackpad likewise would cause the page to scroll down when you dragged two fingers from the top to the bottom of the trackpad.
In Lion this trackpad gesture has been reversed, and instead of providing a quick option to change this behavior, Apple chooses to try getting users accustomed to it by providing a quick tutorial when you first boot into Lion on systems with a trackpad. While the intent here is clearly to mirror the scroll and swipe behaviors of Apple's iPad tablet, it's counterintuitive if you're used to the opposite.
