I've settled into a nice routine for getting eBooks onto my PDA. I don't buy eBooks online, rather I just read public domain texts or other sources (websites,...). I use iSiloX to convert HTML files for iSilo (HTML's from online or derived from .PDF's using Acrobat) or convert .TXT files into .PDB's using
PorDiBle on my Mac. Then I read the .PDB's with iSilo.
It is easy once you know the process and have the tools.
