Subnotebook (Palmtop) Computers

Even smaller than the notebook computers are subnotebook computers, also known as palmtops or handhelds. These tiny systems are 7 inches wide × 4 inches deep × 1 inch high. Due to their size, they are rather limited in function. Keyboards, for example, are too small to permit touch-typing. With notebooks decreasing in cost and weight, palmtops have been losing market share and popularity.
