Credited by many with creating the whole PDA (personal digital assistant) and smartphone category, Psion's golden years were, unfortunately for the company, in an era when such devices were not so commonplace as they are today.
Its EPOC operating system was a forerunner of the Symbian mobile phone operating system, as used by Nokia when the Finnish company was the top mobile phone producer in the world.
Psion sold its stake in Symbian to Nokia for £93.5m plus two year's worth of royalty payments (at 84p per Symbian licence sale) back in 2004, and has been concentrating of late on the design of rugged mobile computing devices.
