Some argue that the Xbox 360(s msft) controller was the greatest one ever made. Perhaps concerned that it was resting on its laurels, Microsoft poured $100 million into developing a new controller for the Xbox One, according to a VentureBeat four-part exclusive. The company researched tons of wacky features: a built-in projector, speakers and even the ability to emit smells. But the end result actually has just a few tiny tweaks from what made the 360 so successful — though those tweaks apparently cost millions in their own right. I guess it’s a small price to pay in the quest for perfection.
