Today is Xbox One's launch day. And plenty of you are probably busy getting set up and playing some of the many launch titles available. We've been at it for just over a week now, and with your Xbox One you'll get the brand new Kinect sensor. With this you can get logged in (once you've made all the necessary calibrations) to your Xbox One autmatically as it has your biometrics down. This means the sensor is capable of pairing the player in front of the screen with the appropriate Xbox Live account.
However, if you make some radical changes to your appearance - such as a visit to the barbershop - you won't be recognised. This was something we experienced (see the before and after pictures).
