Since I noticed you asking about how MindManager and PersonalBrain compare, here are my thoughts. First, I think they really are designed for different tasks.
While MindManager is primarily a brainstorming and task manager tool, like a flat visio diagram that lets you attach files. PersonalBrain is designed for easy integration with files and Web pages from the ground up, to structure all your information on your computer and Internet the way you think.
MindManager splits information up into separate maps, each of which cannot practically be larger than a few hundred items. PersonalBrain is designed to allow tens of thousands of items and files to be integrated into a single workspace. The software offers a dynamic visual display that is infinitely scalable. In fact, this same interface that is in use at the Department of Defense and large Fortune 500s to navigate and visualize hundreds of thousands of objects and databases. It would be very difficult to scroll through a large data sets in mindmanager.
As you know, a Thought can represent any type of digital information on your computer. Clicking on a Thought brings it to the center of the display and all related information then surrounds your active item. This makes it easy to see all related information without the clutter or additional branches. In other words PersonalBrain doesn't need to take up alot of screen real estate to be useful. In fact most of our users leave it on autohide mode whereby they simple click on a icon that appears on there desktop and PersonalBrain opens a quarter way across the screen.
Additionally, this dynamic reconfiguration makes navigation faster and sleeker. There is also a back and forward button to move back to topics. The past Thoughtlist is literally a breadcrumb trail of everything you have clicked on. Add to that, you can click on any topic in the past Thought List to move back to areas of interest. This feature, along with our animation, enables superior navigation. You can even use TheBrain interface to navigate a Web site. This scalability is why Encyclopedia Britannica has OEMed our product dubbed BrainStormer. The latest version of Encyclopedia Britannica uses TheBrain to organize over 78,478 entries, and over 1.3 million article relationships within the Encyclopedia Britannica’s 2005 Ultimate Reference Suite (both DVD and CD versions) and the 2005 Deluxe Edition.
With MindManager navigating a Web site or database would be cumbersome. That is why their conversion to a standard outline view and Web page is so important.I am definitely interested in your thoughts. The experience of the two applications really is completely different!
