I'm not sure how you were using it, but Pivotal was one of the easiest task trackers I've used (used it for all planning and dev work for six months at a previous job). The tasks you're working on just show up in a separate column, and as for moving through states, I don't see how clicking a button to deliver/accept is crazy - you don't even have to reload the page like you do in Trac when you mark a bug as complete.
