Dell formally declares its Adamo XPS, the most recent addition to the company’s Adamo line up, which is the world’s slimmest notebook laptop, measuring almost 9.99mm or else presently four-tenths of an inch. With the swipe of a finger, the keyboard emerges from below the display as the system is open. When opened, the body of the Adamo XPS is lifted so the keyboard is sloping to improve cooling.
