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. The most popular hand-held computers are those that are specifically designed to provide
PIM (personal information manager) functions, such as a
calendar and address book.
Some manufacturers are trying to solve the small keyboard problem by replacing the keyboard with an electronic pen. However, these pen-based devices rely on handwriting recognition technologies, which are still in their infancy.
