It includes the S Pen which is a similar stylus. Notebook 9 Pro has an Active Pen which is similar but different feature set for each. The Tab S6 S Pen has a rechargeable battery that charges when attached to the back of tablet in a little groove magnetically. With the Tab S6 S Pen you can launch shortcut features with the button on the side like accessing a quick notes app like you would with an Active Pen. But with Tab S6 it also gives you some Bluetooth functions where you can launch apps or control media or your camera from a distance. And you can use gestures too, so if you swipe up or down while holding button at a distance it does different things.
