GammaTech, the company that sounds like they gave the Hulk his powers, has introduced a rugged notebook in the 15.6-inch Durabook S15C. It sports a magnesium alloy case and conforms to 810G military standards. The hard drive is encased in a cable that will absorb shocks and the keyboard is spill-resistant.
The optical drive bay even has a lock-out that will prevent it from opening when the notebook is dropped. There is also double protection battery circuits to prevent overheating and over-voltage damage. Yes, they went above and beyond with this one.
