The most important button on the Xbox isn't the power button: it's the button to eject the game disc. Conceptually, this doesn't make sense. Of course, the power button should be the most important button: it turns the entire console on (and off). But that attitude is rooted in our understanding of modern devices, where our games and apps are much more self-contained than they were during the heyday of the original Xbox.
The console layout reflects the priority of the eject button . The drive eject button is larger, higher up, and surrounded by an LED ring in the console's iconic green glow, drawing even more attention.
