In this article Kathy Sierra tells how for her a demo of MindJet MindManager on a tablet PC changed her perception of the TabletPC. It seems to her that this single application moved the Tablet from her expensive toy list to her must have list.
Two points you should take from this article:
- If you don't know how to mind map you should find out and give it a go.
- The tablet provides a much more natural, and therefore more powerful, method of input for information that is structured in a non-linear way. (especially when coupled with software designed to facilitate the task)
In short - give it a try.
