Pros
Pro Intuitive UI with drag and drop support
For the most part, navigating the editor is pretty intuitive - moving around is done by clicking and dragging the background, clicking on nodes will expand/collapse them, dragging and dropping in files will add them, etc. It also offers shortcuts for power users. For example, ctrl + up/down will rearrange ideas up/down, alt +up/down will zoom in/out, etc.
Pro Supports media files, recognizes URLs and commands
Freemind accepts drag-and-drop for any kind of file, URL or command as part of the mindmap. Files it recognizes, like images, will be displayed. Other files will open in a separate, appropriate application. URLs, links to folders, and executable commands pasted in will be recognized and turned in to clickable links.
Cons
Con Does not connect with your mind
As a matter of fact, you have to move your hand, and use your fingers to punch the keys, that makes your mind think and does not free it.
Con Unintuitive UI
Want to add a new node? Right click to free space won't give you that option. Left click neither. No button on the screen for that either, but lots and lots of icons you can put into a selected node.
