Panasonic ToughBooks are the world's most rugged Linux laptops. Models include the Wasp CF-19 tablet, weighing 4.5 pounds, and Tarantula CF-31, weighing 7.9 pounds. Each features a daylight-readable screen (up to 1200 NIT), touchscreen LCD, and fully rugged design for the harshest of environments (independently MIL-STD-810G and IP65 tested). Both offer Linux-supported internal GOBI cellular mobile broadband options. The larger, semi-rugged Scarab CF-52 has a 15.4" 1920x1200 LCD and ATI video, making it an ideal engineering workstation for the field. Look to the 2 pound Ant CF-U1 UMPC for the smallest fully rugged machine anywhere, with a 6 foot drop specification. The Scorpion CF-C1 Tablet with pen input offers great flexibility in a semi-rugged package. The keyboardless Hornet CF-H2 tablet/slate system has dual-touch pen and finger input, and a Core i5, SSD, GOBI, GPS, and more.
