Yup, my only bad memory from the 5mx days... it was awesome to be able to actually code apps for the Psion ON the Psion, on-and-off, in trains, meetings etc. Not even the NITs come close (keyboard, heh).

But it was such a pain to be forced to do it in a new, special language, especially a tormented and tormenting dialect like OPL. And talk about code reuse... when the Psion went, so went the man-days-or-months of sweat 'n tears spent on the code.

Since then when I do still code I only ever touch Python. Apps I made years ago for the Zaurus now run on my tablet, on my Windows PC, on my home server... and I still understand the code, unlike OPL32 :-)

Yes, there was a port of Python for the 5mx at the time ; but like Linux there was no UI integration, so mostly useless.
