As promised last week, Gigabyte has taken the wraps of what it claims is the world's lightest notebook. Say hello to the X11, which tips the scales at a measly 2.1 lbs—less than a kilogram. Much of the weight loss likely comes from the carbon fiber chassis, which employs a wedge-shaped design that's 3- to 16.5-mm thick. The X11 is the only "full carbon fiber notebook on earth," according to Gigabyte, although the company concedes that the chassis does feature a few aluminum pieces, such as the hinge holding the display.
