This piece of software just crossed my keyboard:  MindManager X5 Pro.  I was already familiar with mind maps.  Kent Beck uses them extensively.  And, I’d seen similar software like The Brain.  But, MindManager is so much more than just a mind mapping tool.  It is extremely intuitive.  I was up and running in less than five minutes.  And, it integrates with several Microsoft Office applications, including Word, PowerPoint and Outlook.  I am so impressed that I am seriously considering coughing up the $250 they are asking!
