The updated Apple Pencil, which uses pressure sensitivity and angle detection, adds new gesture controls that allow you to tap the sides of the pencil to switch among tools. Tap twice and you can switch your tool in the Notes app from a pencil to an eraser. The gesture controls are also customizable, allowing you to create shortcuts to difference functions. 

The second-generation Apple Pencil also attaches magnetically to the side of Apple's newest iPad Pro and pairs automatically. And instead of charging via a Lightning connector, it has a new method that allows the pencil to charge wirelessly when docked to the iPad Pro.
