So the iPad’s cool and everything, but…
...who remembers the Psion Organiser?
My old French teacher Mr Johnston (a.k.a. Doss Boss) had a Psion II. He used it as a ridiculously large and clunky Filofax. It was better than the Psion I mainly because it had two lines of text to display rather than just one (with only 16 characters). There was quite a kerfuffle when he upgraded it to 32k of RAM. It had one game on it, which was like worms on two lines. It also had a handy slide-off cover to protect it, which was actually slightly curved instead of all pointy - a big change in the aesthetic that made it look less like a calculator. What else...the letters were arranged alphabetically rather than QWERTY, and it cost £139 new.
