Really good to have the tech-savy in the group as well. I use Mind Manager and find that it serves other purposes for me than hand-drawing. Really good for presenting things in a more orderly manner, and the feature where you can convert a mind map to a Word document, where the subjects and sub-subjects become bullitpoints and sub-bullitpoints is really useful with people that are (initiallly) sceptical towards drawings! Also much easier to change the mind maps later.
But for generating ideas in a thinking process, nothing beats pen and paper 🙂
