I do GTD because keeping the things I have to do external to myself relieves my mind of having to track it all. This extremely enhances my focus and energy. YMMV. We are focusing on people that do GTD as potential customers because they need an extremely fast (keyboard shortcuts), secure, easy-to-look-at way to track everything they have to do. So it may not solve a problem you have, but it definitely solves a problem I had: all the other list apps are too complicated and slow for my taste -- and there has got to be more people like me. Thanks for the comment!
