While the specs of a typical HPC hint at functionality similar to a standard laptop, most devices of this class were used mainly for its personal digital assistant (PDA) capabilities. The device was often used for storing contacts, organizing schedules, note taking, simple calculations, quick word processing, instant messaging and with wireless connectivity, email exchange and Web browsing.
Launched in 1996, the HPC found its market with businesses and individuals in search of mobility. However, Microsoft stopped HPC development in 2000, opting to focus efforts on Windows Mobile - the platform for Pocket PCs and smartphones.
Prior to the HPC's official release, several devices fulfilled the specifications of a handheld PC, even though they ran on DOS-compatible platforms. These were the Atari Portfolio (1989), Poqet PC (1989) and Hewlett Packard's HP 95LX (1991).
Subsequently released handheld PCs include the NEC MobilePro 900c, HP 320LX, HP Jornada 720 and Vadem Clio. Today, devices that run Windows CE with HPC hardware specs but are not equipped with a keyboard are known as Windows CE Tablet PCs or simply "tablet devices."
