It took 75 tries before MS decided on the Xbox One design

 In a recently posted story on Microsoft’s site, the designer of the Xbox One, Carl Ledbetter, revealed that it took 75 prototypes before Microsoft settled on the current console’s design.

75 3D-printed models were made of the system, 100 just for the kinect camera, and over 200 for the Xbox’s controller. It just goes to show how much thought goes into not only the technical specs of a console, but its aesthetics as well.

Ledbetter says that the goal of designing the latest iteration of Microsoft’s popular console was to blend classic Xbox looks with the idea that the system would be an “always on” multimedia powerhouse.
So how long did the entire process take? Two years just for the design of the console. Some other interesting details about the device came up in the article, like the code-name for the Xbox One was “Durango”, and that 40 subtle improvements were made to the controller.
