Drawing on a touchscreen has never been as natural as doodling on paper. An iPad’s capacitive display only records touches that are greater than 4 millimeters—too large for finer details. The tip of the Adobe Ink stylus is just 2 mm, but a specially designed transmitter near the grip of the pen tricks the screen into reading it anyway.
