Your business is tough. That's why Panasonic built a laptop that can handle just about anything you throw at it. These Toughbook computers are manufactured to endure 3-foot drops and to withstand violent shocks and vibrations. They are fabricated to operate at temperatures over 140° and below -20° Fahrenheit and function both at high altitude and under increased atmospheric pressure.  The Fully-rugged Toughbook line includes the 13.3" Toughbook 30, the all new 13.3" Toughbook 31 and 10.4" Tablet Toughbook 19.
