There is a "To Do List" gadget on google if you use igoogle for your home page.

I run 5 of them at the same time:

1. Personal
2. Work - Production
3. Work - Personnel
4. CCA Board stuff
5. Other Conservation .orgs

I also use the google calender gadget to keep track of appointments, meetings and other more important things such as hunting and fishing trips.
