One of the many, many things that Apple does right is trackpads. Not only is the trackpad hardware that Apple uses in the MacBook lineup the best in the world (seriously, I’ve never used a non-Apple trackpad that even came close), but the software backing it up is world-class.
A lot of that has to do with the library of consistent trackpad gestures Apple has built into OS X over the years. Compared to OS X, Windows feels downright schizophrenic when you’re using gestures. Sometimes they work, sometimes they don’t. But it now appears that Microsoft is putting an end to the trackpad schizophrenia by borrowing Apple’s approach to gestures.
