A minimalist, web based to-do list: TeuxDeux
TeuxDeux is a very simple ToDo list manager if you'd like to manage this sort of thing using a web application. Basically, it makes elegant date-based lists. They've mercifully kept feature creep to a minimum. If more complex task management is more than you need, this might be worth a look. Note: On Friendfeed, someone pointed out that TeuxDeux currently has no posted Terms of Service or Privacy Policy. To me, this is a deal-breaker.
Postscript: TeuxDeux now has an explicit privacy policy. It's written in plain English, covers the stuff which I found a concern, and seems entirely satisfactory. Hats off to TeuxDeux for listening to its users!
