Business Rugged Panasonic Toughbook 53 are durable enough for the real world Any business on the move requires technology that can go the distance. With a mobile PC, the display, hard disk and keyboard are the components that suffer the most damage. It’s why Business Rugged Toughbook models really focus on protecting them. Sensible protection for the most frequently damaged components Accidental drink spillages cannot damage the Toughbook Business models because a special drainage system protects the keyboard, touchpad and other sensitive components from splashes, especially on journeys. A full 170 ml glass spilt directly over the keyboard and touchpad simply flows out leaving all electronics in tact.
