Alongside the announcement of the Surface Studio AIO, Microsoft unveiled the Surface Dial accessory.
This is a pretty awesome accessory that lets you scroll through files, pages, and options on apps that you are browsing, with changeable functions depending on the application that you are using.
But on top of that, it can also function directly with the Surface Studio by simply placing it on the screen, once you do you will get access to extended functions for the application that will show on the screen, such as scrubbing through motion sequences or showing colour palettes.
It will also work with a number of third-party applications such as Mental Canvas to edit canvas’ easily.
The Dial will more than likely come packaged with the Surface Studio, however, not much in terms of availability or pricing has been announced yet.
