Part of the reason that I bought a psion was that I saw lots of hacker activity on usenet, so I was confident that I could get my data out of the dang thing and into something else (like emacs) if I wanted to -- and not just the vendor-supported options.
There are quite a few utilities to run on the psion, but I'm surprised at the lack of perl/python/tcl/scheme code to run on the host computer to do stuff with psion files, like convert them to HTML or email or something useful.
Today, I just had to get the data out of my spreadsheet file: I had a backup of the file on my unix box, but no serial cable. So converting it to text on the psion wouldn't help. So I grabbed the (excellent!) psionics files and started hacking. A couple hours later, I had spr2qif done.
