The S-Pen is responsive and there's not too much lag when you're drawing or writing on the screen. It's not just an ordinary stylus, either. Built-in pressure sensitivity means a firm press increases the width of any on-screen drawing or writing. An on-screen cursor can be set to appear whenever the pen hovers close to the screen, without actually touching it. Samsung has also built-in palm rejection support into the tablet, so when you're using the pen you can rest your palm on the screen without accidentally bumping anything.
