In a nostalgic note, The Register, an online news site from the UK, has written an in-depth history of the Psion organizers. This device was, and still is, an amazing piece of technology with many features modern smart phones can only dream of having. I never became a Psion user myself (I went the Palm route), but a few of my friends where huge fans of these devices (mainly the Serie 3 and then the Serie 5). The Psion OS had features equivalent to OLE links on Windows that PalmOS still is lacking today, amazing response speed and great usability. The OS itself lives on in the form of Symbian, used by Sony Ericsson and Nokia for many of their smart phones.
