I totally wrote my own TODO system. It's actually quite featureful, and it works as a command-line program that stores its data in a human-readable text file. And can produce graphs. Admittedly, it's more of a time-tracking system with an attached TODO list than anything else, and it doesn't pop up reminders for anything - I have an annoying calendar for that instead. Maybe one day I'll pop it on github and see if anyone else likes it.
