3. Microsoft's Kinect (Both Times)
https://www.youtube.com/watch?v=p2qlHoxPioM What you were promised: Accurate motion-tracking hardware that would put you in the game. What you got: An unresponsive mess of a product that not only couldn't follow you, but didn't even recognise some peoples' ethnicities. Man, man, the motion n' voice-sensing Kinect was such a ridiculous failure, it's taken Microsoft almost two solid years to rebuild their reputation. First time round on the 360 it was shown off with a horribly saccharine-sweet highlight reel, featuring a load of random people grinning from ear-to-ear as the Kinect recognised everything from individual hand movements to one-to-one movement. Then consumers got their hands on it, and even holding up your arm for recognition returned nothing but blank stares from the machine. It literally didn't work as advertised, resulting in games that weren't playable and ruinously, many dark-skinned users genuinely being rendered invisible by its useless detection software. Come the reveal of the Xbox One, and rather than ditch the wretched creation for good, Microsoft decided to build an entire console infrastructure around its implementation. That went about as well as expected when the thing still couldn't guarantee constant recognition, and as such, the Kinect's very existence is about to be buried for good when the 'New Xbox One Experience' dashboard rolls out in November 2015.
