This one's going to be non-fiction and quite short. I'm calling it "The Charm of Linux". It will basically be a work of advocacy, not a HOWTO.
I think I shall post the chapters up here for people's amusement as I complete them if that's OK with the mods. Here's the first chapter; I've had to disguise it as a .zip file but it's actually .odt (well that is a zip file, isn't it?).
