Dell has unveiled the Latitude E6400 XFR - a rugged touchscreen laptop that meets US military standards regarding withstanding dust, dirt, liquid spills and extreme temperature.

Dell has given the E6400 XFR twice as much protection as a magnesium-alloy laptop offers with a PR-481 hybrid Polymer casing, making it pretty well protected if it's accidentally dropped. Dell cites heights of up to 1.2m as being safe, as long as the laptop is closed and powered down. The Latitude E6400 XFR will continue to work normally after a drop from a height of 36in if it's switched on and the lid is open.

Measuring 353x256x56mm and weighing 3.8kg, the Dell ruggedised laptop is 15 percent thinner and around 5 percent lighter than the last rugged laptop Dell launched.

The Dell Latitude E6400 XFR features a 14.1in 1,280x800 touchscreen display with DirectVue Technology that allows users to see the screen, even in direct sunlight.
