Re: It was the software that made the Psions so great
This reflects my feelings; the Psion worked well because of the combination of hardware and software. Producing a modern version of the hardware alone isn't the main part of the task.
There's a System 3 emulator that escaped from Psion beach in the day for DOS compatibles; you could DOSBox away the problem if only needs hadn't changed. But now the first thing somebody is going to ask for is email, then the ability to edit those Word documents and Excel spreadsheets that he keeps getting by email, then why not throw a browser on, then please just show a normal desktop. So I don't really think you could recapture what the device was.
