Rugged Tablets can be divided into semi-reinforced or fully-reinforced. The semi-reinforced shell has the protection function of anti-drop, anti-vibration and waterproof. Full reinforcement is carefully designed from the inside in place. Unlike portable computers, Rugged Tablets don't require a cooling fan, and only pass internally to the external shell to naturally passively dissipate heat, thereby improving the performance of dust and water resistance. Rugged Tablets are lighter, thinner and easier to carry than portable computers, and tend to have low power consumption and low heat in terms of hardware performance.
