I started reading the link and sort of had to pace myself over a whole day to read the 10page article ... *phew* ... but it's a good read!
I never really got into Psions but saw them as expensive goodies on shelves that was out of my reach as a student back then. But I got myself a new old Diamond Revo (basically a remarked Mako, or was it the other way round?) and boy, was I thrilled! As always, the ridiculously long batt life, speedy response of apps, without a compromise in usability ... in fact, most who own(ed) one would attest to their superiority!
Anyway, just some good news for Kohjinsha users ... installing the Psion 5 SDK gives you all the emulator goodness! Remember to install AlarmPlusWin (not AlarmPlus, as they binaries are not for the windows emulators) so that your preferences, like home timezone is saved.
Now I wonder whether I should create one user account to load the emulator as the default shell so that the system simply appears as an over-sized psion 5, or a psion 7 (Netbook!) ...
You can also install psion 3 or psion 7 if you like.
