To do or not to do will never be the question.  A to-do list should, well, be only a to-do list. TeuxDeux does just that. A simple view of my week with items to fill and nothing more. Since they know the human tendency to procrastinate, they have a ‘Someday’ field for backburner items. Clever. It’s available on the browser as well as the phone. We love it. Thank you, SwissMiss and FictiveKin for creating it.
