Yet another vote for MindMapping.
I'm an MD/PhD student, and the first student to use a windows tablet with onenote for all my medical school notes and research activity.
I can tell you its setting a trend cause frankly, IPad's and even windows tablets without a wiacom pen do not compare to what I am able to do with my Samsung Series 7 tablet using onenote.
I know at least 4 others that have made a transition to use OneNote on their laptops instead of their IPads...HOWEVER!!
#1 complaint is the LACK of an integrated MindMapper: I understand linking onenote pages and the like, however, OneNote needs a mindmapper that allows future editing without loosing structure/connections as you would with a makeshift mind-map via inking.
You wanted customer Feedback, here it is. Add a feature packed integrated MindMapper to OneNote.
P.S. I'm on the verge of purchasing that GEM Add in solely for the MindMap feature...however it doesn't seem to let me try it before I buy it.
