The fan-less 11.6-inch Windows tablet is guaranteed to survive through shock, vibration, rain, dust, sand, temperatures as high as 140 F (60 C), and a drop of up to 6 feet without a sweat. The rugged and fully closed system competes directly with the Dell Latitude Rugged series also designed for extreme conditions.
