Microsoft has filed a patent with the United States Patent and Trademark Office (USPTO) that shows a mobile phone that has a slide-out pad that is interchangeable. The Different pads shown consist of a game controller with a thumbstick, a keyboard, an extra battery, and a second screen. There could also be other possibilities that weren't shown.
The image from the patent shows the four different interchangeable slide-out pads. The '1980' is pointing to the empty space where the different pads are placed. The versatility is a nice change, however it may be expensive and it will increase the thickness of the phone.
