Only a capacitive stylus will work on the 1520. Your Surface Pro 2 stylus isn't capacitive, it's uses Wacom technology and requires a special sensor layer under the screen which the 1520 doesn't have. But you can use any stylus that will work with an iPad, the kind that has a soft foam tip. They sell them at Staples, Future Shop, Best Buy, Walmart, etc. The good news is the 1520 works extremely well with a capacitive stylus because the touch screen is so sensitive.
