on this i have to disagree - allthough im not certain in what context that you think it should used?
I use mindmap a lot for not taking, minuting and brainstorming an idear. Outlook, access and those other programs that you mention are for totally different purposes.
I newer use it for presentation for others - only for my self. Mostly because a lot of people seems to have a "block" against such things and i dont want to shove it down thier throats.
I just sometime find it easier to use software instead of a hand drawing.
Best regards
