It featured a large monochromatic LCD screen protected by a plastic stylus, which was necessary to interact with the on-screen keyboard and applications. Technical Specifications and Limitations The technology behind Simon was groundbreaking but inherently limited by the standards of the late 1990s.
Simon combined a mobile phone, pager, fax, and email device into a single unit, allowing users to make calls, send faxes, and access a rudimentary calendar and address book all through its touch interface. The interface was fluid and responsive, rendering the stylus obsolete and proving that a direct, finger-based interaction was the future of mobile computing.
