There is a picture floating around somewhere that when Microsoft was presenting their console, allegedly, they were actually using a titan graphics system to display their games.
They also had to make changes to the Xbox One due to the fact that no one was going to buy them. Their new system was, and probably still is, pretty invasive. They have the right to ban you for any reason they deem reasonable, the Xbox One has 24 hour online check-ins, the Kinect camera has to be plugged in an on at all times for the Xbox One to work, etc.
But since people were unwilling to buy their incredibly invasive system they took all that off.
