Apple has long implemented multi-touch scrolling on its notebooks via a two-finger scrolling gesture, however the new version of OS X 10.7 shows the direction that Apple may be headed in merging its full OS X operating system, found on notebooks and desktops, with the mobile iOS operating system, found on iPhones, iPod Touches, and iPads. With OS X 10.7, codenamed Lion, Apple will be inverting its scrolling movement to more closely resemble the scrolling gestures on the tablet and phone.
With Lion, the default scrolling motion to scroll down a long page, like a Web page, is to use two fingers on the multi-touch trackpad and flick up. This gesture is akin to users actually pushing the page up to view the hidden contents below. The older scrolling gesture to scroll down a long page is to use two fingers and swipe downwards, a movement that aligns with the direction of scrolling.
If users prefer the older system, they can definitely revert back to the older gestures, but developers who got an early preview of OS X 10.7 Lion noticed the change in scrolling behavior.
While a tablet running the full Mac OS X operating system has been a dream to many who would prefer the desktop operating system’s power to produce content, recent changes in Lion may indicate that Apple may be moving the mobile and desktop OSes closer together.
