Design consultants Teague were responsible for the green and black monolith that was Microsoft's original Xbox. Now two designers from the firm have used their console-creating experience to review the aesthetics and ergonomics of Sony's PlayStation 4 for Fast Co. Design. They judge its positives — including the "emotional" light bar that's found a secondary use as a signifier of broken consoles — and its perceived negatives, including its sloped shape and disc drive placement. The designers also weighed in on the console's updated DualShock controller, praising the slight increase in scale to make it more comfortable, but highlighting a "design disconnect" between the pad and the console it belongs to.
