The Psion returns! Meet Gemini, the 21st century pocket computer

Psion, was a lion, in iron (Reg readers called it)

Exclusive The original Psion designers have returned to put the classic British pocket computer in a modern body.

Martin Riddiford, the designer of the Psion Series 3 and Series 5 keyboards, and co-founder of Therefore, has come up with an entirely new design for the 21st Century. Patents were filed today, and the venture codenamed “Gemini” has launched on Indiegogo.

Therefore co-founder Jim Fullalove explained to us: “It’s a modern 64GB smartphone feature set, but with a beautiful new full travel compressible keyboard from Martin. The keyboard compresses under a magnetic spring force.”

A new venture backed called Planet Computing is behind the new device, led by Dr Janko Mrsic-Flogel, a well known software author in the Sinclair era, and backed by Therefore, amongst others. The team will be using Indiegogo to help fund the project.

Gemini basic specs ... Click to enlarge

We'll have a hands on with you shortly, but for now, here are the specs. Gemini is using very contemporary hardware: specs suggest Gemini has two weeks' of standby time and weights 400g, measuring 71 mm x 80mm x 135 mm. 4G and Wi-Fi are supported. The display is a 5.7 inch diagonal panel - a little larger than the old Psion Series 5 but not by much.

Gemini will be dual platform with Linux and Android supported. But future variants may take it in other directions.

British pioneer Psion launched the Series 3 in 1991, and the Series 5 in 1997. The pocket computer had a multitasking rich operating system and application suite, but was best known for making touch typing possible on a relatively low cost and convenient device: one that fitted a jacket pocket, back when laptops were cumbersome and expensive.

But the company's last PDA was a Revo in 2000 - 17 years ago.


It's 10 years since we published an extensive history of the "last British computer company" - featuring interviews with the key figures including Sir David Potter, Martin Riddiford and Mark Gretton.

The Psion was the retro technology that Reg readers most wanted to see return.

Stand by for a full story on how this much-loved computer design made its return. ®

    Surveillance tech faces trade limits as America syncs policy with treaty obligations

    More than six years after proposing export restrictions on "intrusion software," the US Commerce Department's Bureau of Industry and Security (BIS) has formulated a rule that it believes balances the latitude required to investigate cyber threats with the need to limit dangerous code.

    The BIS on Wednesday announced an interim final rule that defines when an export license will be required to distribute what is basically commercial spyware, in order to align US policy with the 1996 Wassenaar Arrangement, an international arms control regime.

    The rule [PDF] – which spans 65 pages – aims to prevent the distribution of surveillance tools, like NSO Group's Pegasus, to countries subject to arms controls, like China and Russia, while allowing legitimate security research and transactions to continue. Made available for public comment over the next 45 days, the rule is scheduled to be finalized in 90 days.

  • Global IT spending to hit $4.5 trillion in 2022, says Gartner

    The future's bright, and expensive

    Corporate technology soothsayer Gartner is forecasting worldwide IT spending will hit $4.5tr in 2022, up 5.5 per cent from 2021.

    The strongest growth is set to come from enterprise software, which the analyst firm expects to increase by 11.5 per cent in 2022 to reach a global spending level of £670bn. Growth has fallen slightly, though. In 2021 it was 13.6 per cent for this market segment. The increase was driven by infrastructure software spending, which outpaced application software spending.

    The largest chunk of IT spending is set to remain communication services, which will reach £1.48tr next year, after modest growth of 2.1 per cent. The next largest category is IT services, which is set to grow by 8.9 per cent to reach $1.29tr over the next year, according to the analysts.
