What flavor of stylus hardware does this one use? Wacom AES? Wacom EMR? USI? Something else? Knowing this would tip Lenovo's hand to how seriously they consider this for the art/design crowd. Latency, parallax, etc are important purchasing criteria for at least some of the users this is aimed at. This is clearly not meant to be a graphics workstation replacement but there are Windows devices at similar price & specs with very good stylus/screen tech. I'd love to see this one succeed in this space.
