Appleis MacBook Air is currently the only Mac that offers enhanced multitouch trackpad support, but that could change with nothing more than a software upgrade. An Apple spokesperson confirmed that the feature is software-based, meaning it could be added to current MacBook and MacBook Pro models through a software update, according to T3.
The MacBook Airis multitouch trackpad lets users navigate Web sites in Safari, flip through images in iPhoto, and navigate the Finderis Cover Flow view with finger-based gestures. Extending the feature to Appleis other laptops could lead to third party application developers adding multitouch support to their programs, too.
Apple hasnit said if it plans on adding multitouch trackpad support to its current laptop lineup, or if they are leaving that to creative hackers.
