It's a substitute for the touchpad, but much more precise and controllable, while also being located bang in the middle of your keyboard, so you don't need to change hand position when going from typing to moving the cursor and vice versa. It's an objectively superior experience to the touchpad and after getting used to it I refuse to ever touch a notebook that doesn't have a nipple ever again in my life. It's that good.
