What's the best Mind Mapping Software?
I like FreeMind 
very much, which is a Java mindmapping tool. Colleagues of me like XMind most.
XMind has better graphics than Freemind but it's much heavier.
Pro's include:
- Good customizable GUI.
- Available for any major platform.
- There's a portable version for the USB.
Con's:
- It's java based. That makes it a bit slow.
Try using Freeplane .
Freeplane is a powerful and free software for building the mind maps. It is a redesigned version of the well known FreeMind, and is created by one of FreeMind's key developers. I prefer it over FreeMind since there are more options. Also, questions or problems with the program are answered and fixed MUCH faster.
