    The first shot of the next era :

    The Psion Series 3 is an emblematic Machine. Psion begun it's success story with this model, and the Series 3 had many children; series 3a, series 3c... Up to newer machines including higher technologies or a stronger marketting design, namely the Series 5 and Siena.
    The series 3 deserved the success it met : with an excellent finish, with very useful and well-thought applications; and even a built-in programming language, it was packaged to please any kind of user.
    As for the interface, it's also a good illustration of the "pocket computing turn". The psion integrates a powerful graphical multi-task OS which conception focuses very much on the needs of a small device.
    This OS, later named Epoch was to be used as the basis of the Symbian OS, supported by several pocket devices manufacturers.
    However, after a wide range of excellent product and a large user recognition, Psion was to be overwhelmed by the Palm wave and eventually quit the PDA market...
    This Series 3 is thus the first one of a now defunct breed...

    This machine was very appealing to me at the time, mostly because of it's powerful integrated OPL programming language. However, marketted as a PDA, and thus packed with a powerful V30 16bit processor and lots of applications, It was too high priced compared to BASIC pocket computers.
    When i added this one to my collection, there was no deception at all! The machine was just as i expected, powerful, full-featured, and very pleasant to use... I expected this model to be quite dated, even compared to the later series 3a or 3c; and instead, i found it very ahead of it's time.
    Congratulations to those people at Psion, and too bad they stopped producing such jewels! May the Epoch spirit live long through the Symbian licence!
