I was just talking about Tasks Pro today with Roland. I tried out the original single-user version, Tasks, and was pretty happy with it.
We both talked about how we think/write in outlines, but it doesn't actually seem to work that well for tracking stuff. Tasks is currently the forgotten step-daughter of my electronic world. My phone handles contacts and calendaring, but the tasks part doesn't seem to work for me.
Maybe it's time to give something like this a try. I still like PHP Collab as a project management tool, but there is something to be said for easy, light interfaces. And RSS feeds and iCal support everywhere, of course.
