Microsoft does do some great UI in some of their products. The Xbox One is a console that looks like it has a great way to navigate between games, media, and applications.
The video below shows off the power of the new Kinect camera for not just for gaming, but for navigation and for conversation. I really like how easy it is to use your voice to switch between activities and the console sure does switch quickly between everything.
I did see some pause, rewind, and fast forward commands when viewing TV so I wonder if there are some time shifting capabilities built in when watching live TV.
The Xbox One will be out on November 22nd.
