I see the Reg have posted a long and detailed article on the history of the Psion Series 5, launched 10 years ago. It's a good read and includes a number of interviews with some of the big brains behind the Series 5.
The Psion 3mx has followed me for years, but are there a good replacement - especially I want the spreadsheet and word applications to be good and as handy as the 3-series. Regards
