I dont think the author thinks kinect is wrong. What he criticizes is that a touch interface we you physically touch something needs to supply tactile feedback.

Kinect however is IMO not bound to the same scrutiny for tactile feedback. If you take the Kinect Sports games, you can pretty much see yourself in the game in 3d, making it really intuitive and very natural to move to the game. I agree though, the menu navigation in Kinect is horrible.
