If, however, you are actually planning to scale Mt. Everest, you might want to look into the 6 pound, 8 ounce GoBook XR-1 from General Dynamics. It features an Intel Core Duo 1.83GHz and various memory and hard drive configurations in a case designed to withstand the most torturous situations, and General Dynamics is a defense contractor, so they actually design torturous situations. Maybe it’s a form of reverse engineering or something.

The system also includes glow in the dark keys, many wireless options (WLAN, WWAN, Bluetooth and GPS), a dedicated external graphics controller and can be equipped with fingerprint and/or smart card readers. It’ll set you back $4300 before all the clearly necessary upgrades.
