Dear Howard,
Thanks for listening Productivity Cast! I have never used Thinking Rock. I begin on a Palm, move from there to OmniFocus when was released and last year to Todoist.
That said, I beleive that your productivity software it is like a camera. The one you use and carry with you it is the best one.
Thinking Rock give you a room for an incredible amount of details, that I am sure allow you to plot and dice in the most effective way. I will love to learn more about how you use it.
