Video - The new Apple Pencil

It supports surface pressure recognition, to change the width of lines as you draw

The Apple Pencil was designed to be used with the new iPad Pro, and looks and feels like the familiar tool. It supports surface pressure recognition, to change the width of lines as you draw: press harder to draw thicker lines, or lighter for hairlines. The system scans twice as often when you use the Apple Pencil, capturing more data points in a stroke. Apple Pencil works with Apple's apps as well as selections from the App Store.
