I tried using your system, because it really appeals to me. Unfortunately, I found I had too much engrained muscle memory in terms of my note-taking system, and couldn't successfully convert to your system, even though it is WAY better than my own. In my new job, I also have less meetings, and so fewer notes. At the desk, I rely on the d3 tiddlywiki to manage my life. I just wish I could use my Mac at work, because life is so much better managed with OmniFocus.
