I use a free, web-based to-do list called, whimsically, Teux Deux. I am a list-maker and a list item crosser-outer, and Teux Deux gives me the satisfaction of crossing out items once I complete them, and then deleting them altogether.
If you don’t complete today’s task, simply drag-and-drop it into a different day on the calendar, or wait until the clock strikes midnight, when all of the items on today’s list automatically get routed to tomorrow’s list. Slick.
