Well, in your list of project management software you left out the best one (in my opinion).
I have been using Jumsoft's Process for a while now, and they just released Process 2 Beta 2. -
Process 2 is amazing! - not only does it look and feel like an X app, but it interacts with X nicely too. It easily integrates with iCal and ToDo's - which dump onto your ipod. Plus, using bonjour (with no setup necassary) you can share your projects over your network with other mac users running Process 2.
Now, it's not free, but its worth every penny - especially if you need some collab effort.
Anyway, I'll try and send you an audio review before your next podcast if i can.
