A little kinetic scrolling with Smart Scroll X
We've actually posted about Smart Scroll before, but the video is a pretty good demonstration of what's happening here. I'm not quite sure this is something Apple will want to implement in the OS, however — it feels right enough on the iPhone, but I kind of like that my scroll wheel stops when I tell it to. If you'd rather have the iPhone experience on your usual Mac, however, the app is available as a free trial, or a complete license for $19.
