Microsoft tested Xbox One controller with built-in screen, found it "detrimental to core gameplay"
“SmartGlass is different because it’s for extra information.”.
CVG’s just published a neat little feature on the Xbox One’s controller, which apparently cost $100 million to research. The pad is perhaps the most conservative of the next generation controllers, a refinement of the existing, much-hailed Xbox 360 pad that sports motorised triggers, a proper D-pad and superior wireless bandwidth. That wasn’t always the idea, however.
