Panasonic Toughbook 31 -- $US5798
This laptop can survive 6-foot drops and extreme shock, vibration, humidity, altitude, rain, dust, and sand. It's fully MIL-STD-810G certified. This sort of durability doesn't come cheap, though: You'll pay almost $6000 for this Core i5-540M-equipped machine with a 13.1-inch screen.
