I've been constantly switching tools that keep track of my to-do list:
- Online account in SimpleGTD
- To-do applet in my RSS aggregator
- Outlook's builtin Task List
- My cellphone's built-in to-do list
- Post-it notes on my monitors at home and at work
- Paper list in my wallet (thought about enhancing it and adding a pen like Jeff Atwood did)
Which proved most useful for you?
