Surface Touch Cover

Surface Touch Covers were accessories developed by Microsoft for their early Surface mobile devices.

History
The first Touch Cover came with 80 touch sensors and was pressure sensitive. With the release of the Surface 2, the Touch Cover 2 was announced which increased the number of sensors to 1,092 and added backlit keys while being thinner than the original Touch Cover. In addition, the Touch Cover 2 also supported key gestures and was backwards compatible with the first generation Surface devices. Microsoft never made another Touch Cover after the release of the Surface Pro 3.
