Think of Dell business laptops and you might get an image of white-collar workers sitting in an office or aboard a plane, typing away in a comfortable indoor environment. But in situations where someone needs to work outdoors or anywhere that's exposed to dust or harsh weather, an ordinary laptop probably won't cut it. You need something tougher. The Dell Latitude ATG D620 ($3,126 direct) is Dell's first attempt at the semi-rugged space. Its outer casing has additional padding to withstand dust, spills, and a heap of other outdoor accidents. Just prepare to pay a pretty penny for such protection.
