Panasonic has added the Toughbook to the vast range of Android tablets on the market now, with the clue in its name that this one's different due to its rugged build and security system. Unveiled  at the Defence Security and Equipment International (DSEi) at Londons Docklands, the Toughbook features a stylus with a 10.1-inch XVGA (1280x1024 pixel) antiglare touchscreen display with 5:4 aspect ratio – figures that will definitely offer high brightness and greater viewable angles even under direct sunlight. The tablet has deep rooted security measures embedded at hardware level. Other features include satellite-based GPS, full-shift battery life, professional-grade accessories and optional in-built 3G mobile broadband connectivity.
