The Sharp Zaurus ZR-5800 — Japan’s PDA Leader
The Sharp Zaurus series was Japan’s most successful PDA platform — a range of handheld computers that dominated the Japanese PDA market throughout the 1990s and early 2000s while remaining largely unknown in Western markets. The ZR-5800 ran Sharp’s own Zaurus OS on a StrongARM processor, offering a touchscreen interface, handwriting recognition, and a comprehensive suite of Japanese-language applications. Later Zaurus models would move to Linux, making Sharp one of the first major manufacturers to adopt open-source mobile computing. In Japan, the Zaurus was to PDA computing what the Palm was in North America — the default choice for mobile professionals.
