The Dell Latitude E6400 XFR is a 14.1" rugged business notebook, based off the standard E6400 with a new chassis built around the same internal components to make it rugged and waterproof. The chassis offers completely dust and weatherproof access panels covering all external ports, rubber bumpers, and a built-in carrying handle for easy transport. One area that Dell stands hand and shoulders above other rugged notebook manufacturers is the inclusion of high-end components, including dedicated graphics, instead of taking a low-voltage and low-heat approach. In this review we put the Dell E6400 XFR through a battery of tests, to see how well it stands up against other fully-rugged notebooks.
