Microsoft has reportedly been working on a mysterious new Surface device for at least two years.

Codenamed Andromeda, the device has appeared in patents, reports, and in operating system references multiple times and will include a dual-display design. According to a Microsoft internal document, it’s also going to fit in your pocket.

Andromeda is still being developed, but is said to come with a wraparound display that bridges the gap of the hinge when fully opened – and may include a stylus.

Microsoft describes the Andromeda project as something that will create a new and disruptive device category to influence the overall Surface road map.
