The previous models included a Wacom digitizer in the screen and used a passive stylus. This time around, it’s an N-Trig digitizer and an active—which is to say battery-powered—pen. I’m not entirely sure what motivated the switch from Wacom to N-Trig; I would guess that it’s because N-Trig’s “DuoSense” sensor, which combines a capacitive multitouch sensor with an active pen digitizer, allowed the screen unit to be made thinner. Making the screen thinner is of course important for the overall dimensions of the tablet, but it’s also specifically valuable for pen-driven applications: the thinner screen means that digital ink appear closer to the pen tip, reducing the parallax effect that otherwise exists.
