You can use the controller and voice at the same time, and probably hand gestures with a much more accurate Kinect 2.
Searching from the dashboard is already good enough to be useful over a controller alone. Natural language support and properly integrated voice should be a huge improvement. Snapping the browser or a YouTube app in next to a game and searching with voice and gestures should be easy.
You can still use tablets/phones, but this brings a lot of useful stuff to your TV with, I am hoping, a great and intuitive UI.
