Wow. Kudos for this. The dedication must be extreme. Respect.

And so much learned during this project <3

I wonder if someone would do the same for Psion. I always thought they were the better organiser by far. Both the 3-series and 5 (which had much worse screens but much better OS with multitasking).

I don't have the energy to do this myself :) Though I did mod my old 5mx with a bluetooth adapter.
