The Surface Studio is the very first PC made by Microsoft. The 28" PixelSense touch screen display has a zero gravity hinge so it can be used upright or tilted down to be used like a drafting table. It has a resolution of 4500 x 3000, and 192ppi.
Microsoft also introduced a new accessory called the "Surface Dial" to be used on the display. Placing the Dial on the screen gives you tools like a color picker or a ruler.
