The Gemini PDA is a personal digital assistant designed by Planet Computers in association with Martin Riddiford, who previously worked on the Psion Series 5 in the 1990s, and crowdfunded via Indiegogo in 2017. The Gemini bucks the trend of modern smartphones in its screen being primarily used in landscape aspect, and having a keyboard, i.e. taking on the form of a subnotebook.
Prior to January 2018, pre-production devices were made available to reviewers, and mass production was in full swing in December 2017 with devices starting to ship in late January 2018 to Indiegogo backers.
