Psion: The Last Computer

The article discusses Psion's groundbreaking Protea project, which led to the creation of the Series 5 pocket computer. This project marked a significant achievement as Psion developed new silicon, an operating system, middleware stack, and applications from scratch in just over two years. The Series 5 was a triumph of creativity and management, being one of the last instances of creating a general-purpose computer from the ground up. Despite Psion's innovative endeavors, the company eventually shifted away from consumer electronics, with former staff members going on to lead successful ventures in related fields. Psion's legacy lives on through the Symbian OS, which powers over 100 phone models and remains a significant revenue generator. The article highlights Psion's engineering prowess, particularly in software development, showcasing the company's ability to create high-quality applications with minimal resources. Psion's Protea project exemplified extreme efficiency and innovation, setting a standard for software development in the industry.

The last generation of Psion's in-house C++ Arm32 OS, Symbian, is now FOSS:

Please, please, someone revive this. It was a pleasure to use.

Junk as much as possible of the idiosyncrasies and slap a standard GUI toolkit on top, like Qt or Gtk or something.

It already has a POSIX layer:

It's as if BeOS had been open sourced and nobody noticed.

It's more complete and more functional than Genode, for instance. It runs on bare metal, unlike Serenity OS.

Fun story: the psion5 was faster in certain java microbenchmarks than the HP K-series minis we had at a large bank.

Man, I always wanted a Psion. Never got around to it.

Back then I was a serial adopter of electronic organizers. Plenty of them were neat enough on their own, but only a few of them were smart enough to allow for easy backup, or (better yet) desktop access.

Interestingly, the Newton did this really well AT FIRST, and included a "Newton Desktop" tool that ran on Windows -- but abandoned that with the rev to 2.0. You could still back up to your computer, but you couldn't use the data there. It was a wild misstep, since just around the corner was Palm with its connectivity-first handheld that was also half the price and could fit in your pocket. Oops.

Missing (2007), although it is evident from the URL.

> Software components were the latest buzzword, as “Web 2.0” is today. Experts predicted that the application would disappear, with users selecting from palettes of functional components. Huge investments went into frameworks such as OpenDoc (backed by IBM, Novell, and Apple) and Microsoft, with its OLE.

You know, I wasn't involved at the time but I understand why the experts would have thought this. And perhaps it wasn't too off base, we just don't recognize the reality because 'functional components' turned out to actually be, like, npm packages or something.

I had one of these and worked my summer job while on a bus tour of Europe with family on it. They were amazing.

I learnt to program on a Psion as a ten year old.

I wish Riddiford made a Bluetooth keyboard instead of tying it to the Planet pocket computer.

As the article is from 2007, shouldn't it say so in the title?

I think the title needs a 2007
