Surface Pen Vs. Apple Pencil
Apple's first stylus for the iPad Pro is called simply Apple Pencil and costs $100. It comes packed with some pretty cool tech, including several sensors on both its case and the tip that can detect the position, pressure, angle and orientation of your strokes. Two sensors on the tip work with Multi-Touch display to detect whenever you're tilting the Pencil to create a shading effect.
The Apple Pencil has a Lightning connector at the eraser end of the stylus. Apple boasts a 12-hour battery life for the Pencil. Run out of juice? Apple claims charging the Pencil for 15 seconds will give you 30 minutes of battery life.
Microsoft calls its active capacitive pen simply the Surface Pen, which is included in the price of the Surface Pro 3. Sold separately, the Surface Pen will run you $50. Microsoft says the stylus supports 256 levels of pressure sensitivity and uses palm-blocking technology so you can draw, take notes and mark up documents. Unlike the Apple Pencil, Surface Pen uses disposable batteries to power the stylus.
