Re: Article to read, about E90 and Hildon.
 

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.
