The Sharp IQ-8100M — IQ Series Business Organiser
The Sharp IQ-8100M was a business-oriented model in Sharp’s IQ organiser range — targeting professional users who needed more sophisticated personal information management than basic consumer organisers provided. The IQ-8100M’s enhanced business features, including expense management and more sophisticated scheduling capabilities, positioned it for the executive market that also considered Psion Organisers and later Palm devices. Sharp’s commitment to the organiser category throughout the early 1990s reflected the growing recognition that mobile personal information management was becoming essential for business professionals.
