What is a Handheld Computer?
A handheld computer is a portable computer that is small enough to be held in one’s hand. Although extremely convenient to carry, handheld computers have not replaced notebook computers because of their small keyboards and screens. Traditional hand-held computers were PDAs and devices specifically designed to provide PIM (personal information manager) functions, such as a calendar and address book. Today PocketPCs, smartphones and tablets are common consumer devices.
