Is This The Surface Phone?

Microsoft has revolutionized laptop designs with the Surface and Surface Book, so why not smartphones?A 2015 patent (published Mar. 23) doesn't explicitly name the device as a smartphone, instead showing a technology that could take the form of a "hinged display device" (think futuristic flip-phone).The device would use a "support structure" to contain the displays, and the patent often mentions it as a hinge.
