One of the secret new features of the new MacBook Pros is inertial scrolling, which causes the trackpad to function like the iPhone’s touchscreen when scrolling; in other words, your screen scrolls with momentum informed by how hard and fast you swipe your fingers down or up.
TUAW has a post up about the new feature, positing that it should be possible on “all multitouch Apple trackpads. They’re wrong: the feature should already be possible on every Apple touchpad out there, multitouch or not, as indicated by the SuperScroll software.
The big question is: if all Apple touchpads are capable of inertial scrolling, does the functionality in the new MacBook Pros indicate Apple will roll it out across all Snow Leopard machines in a forthcoming update?
How do you feel about inertial scrolling? Is it something you’d use if it was rolled out to existing Apple laptops? Let us know in the comments.
