context_page_description: The Psion Series 3 range of personal digital assistants were made by Psion PLC. The four main variants are the Psion Series 3, the Psion Series 3a, the Psion Series 3c, and the Psion Series 3mx, all sized 165 × 85 × 22 mm. In addition, a Psion Series 3a variant with factory installed software for the Russian language was called a Psion Series 3aR, and Acorn Computers sold a rebadged version of the Psion Series 3 and 3a marketed as the Acorn Pocket Book and Acorn Pocket Book II.
  The Psion Series 3 range is regarded by writer Charles Stross as an unsurpassed PDA because of its long battery life, its stable and versatile software, and its durable hardware. About 1.5 million Psion 3s were made.
  The Psion Series 3 models were a major advance on the Psion Organiser. They had an original way of managing files: the available program icons are shown in a horizontal line and the associated files drop down beneath them. Manufacture of Psion 3s was discontinued in 1998 shortly after the launch of the Psion Series 5 and the Psion Siena.
