What program do you all use for To-Do lists?

I am looking for a good program to use to keep my hectic schedule organized and layed out. I have toyed around with ICal briefly but it seems built more like a calander (Go figure?) than a daily planner.

Really, all I want to be able to set priorities and add and remove events/notes quickly...any suggestions?

High Priority
Check Off

I've used these two before, they work great, but I never remember to look and see what I have to do...

For work, believe it or not, I use Excel! I keep a priority sorted "To Do" list in an Excel sheet. It has a To-Do tab and a Done tab. I move tasks from the To-Do tab to the Done tab as I complete them. I add new tasks to the To-Do tab as things come in, and reprioritize/resort the To-Do list in "real time" as they come in as well, to ensure I am always working on the most important thing.

I have used this setup for years and it seems to work well for me.

As much as I love excel, its just way too frustrating to use it on OSX. But thanks for the tip! I realize that to-do lists are HIGHLY personalized, and everyone has their own system. I was using the To-Do list feature on the Google/IG homepage system, but for some reason it does not work in Safari. It works in firefox/camino...but not safari (which is my primary browser).

I use my Palm so I guess it's the Palm Desktop Software.

(sorry, duplicate post)

Despite all the technology available to me, I use this.

Works like a charm and doesn't require a charger.

I use sidenote and, like caribiner23, I also like the pen and paper option in the shape of a Moleskine.

What about stickies?

I use stickies and Ical.
