Dell has built a reputation as a supplier of rugged tablets, and the Latitude 7220 Rugged Extreme Tablet is a strong addition to the range. It has undergone military-grade (MIL-STD 810G and 810H) testing (including transit and operating drop-tests), can work in temperatures ranging from -28°C to 62°C, and is IP65 rated for dust and water resistance -- as befits a tablet that's made to survive the toughest of conditions.
