Itronix Gobook XR-1, Heavy Duty Laptop

It can't get more ruuged than The Gobook XR-1 from Itronix. The screen can be dimmed to a level that looks completely dark, but that can be read with night-vision goggles. The notebook can be fully submerged and is designed to survive a fire. If it's cold outside, the system warms up the hard drive before it fully boots. And it can find a wireless network almost anywhere in the world with built-in radios for multiple bands of both UMTS/GSM (Universal Mobile Telecommunications Service/Global System for Mobile Communication) and CDMA (Code Division Multiple Access) cellular networks, plus Wi-Fi, Bluetooth and GPS (Global Positioning System).[source]
