Rugged computers such as rugged laptops have been designed from the ground up for use in outdoor, dusty or mobile conditions. Every component, and even the placement of those components, has been carefully considered.
Rugged Tablets are designed to be lightweight and carried in one hand. Rugged tablets are thus easier to use and handle than a rugged laptop which normally requires a surface to set the computer down while in use.
A rugged handheld computer is a compact-sized computing device that is small enough to hold with one hand, and is durable enough for use outdoors and in other tough mobile computing environments. Rugged handheld computers typically have a display screen with stylus and/or touch input and a compact keyboard or numeric keypad.
