One of my favorite features on the Xbox One is voice command. I love saying "Xbox on" or "Xbox, turn off" to power on or off the console. This isn't possible without a Kinect and it's not available in all regions. There's another way to power up the Xbox One in addition to pressing the power button on the Xbox One console or controller. You can use the Xbox One SmartGlass app on Windows Phone. This is very handy because our phones are usually already in our pockets.
