I've played with tons of the tools, and many of them are very nice (lifebalance, pocketthinker, that mind map thing, the outlook plug in, etc.). And at first they all work very well, then I end up spending a lot of time fiddling with the tool and not really doing the basic GTD steps - which is what i need to focus on. So, I always end up back with vanilla outlook (tasks, calendar, notes) along with VimOutliner for project brainstorming (which saves the notes inside the task as plain text).
