Ruggedized mobile computers
Some professionals work in environments that may require special ruggedized features to protect their computers from extreme tem ature, humidity, and physical punishment. Construction, public service, distribution, repair service, and utilities are some of ronmentally demanding professions that may require rugged mobile computers that can withstand stresses. For these applications, IBM offers such computers (not ThinkPad systems) especially designed for mobile professionals who need a system for managing and com- municating information from the field.
