Of course the other thing that PC mind maps don't do easily is images. That is, sometimes it's easier to represent something visually on a mind map than to write it in words, for example on a recent mind map i was trying to explain the importance of balance between stagnation and indecisiveness... instead I just drew some scales and put those words on either end, which is much easier for me to remember... doing this on a PC package means browsing through stock images, clipart or drawing it yourself - all for me detract from the activation at hand and perhaps filter out some of that "whole mind thinking" approach...?
Just my thoughts. There's a great example of how personal mind-maps can be on Alex's website:
