The second example is using a great app called iThoughtsHD. This app is very much like the program Mind Manager (in fact, you can export to a Mind Manager file type). For school, in general, it is a great way to brainstorm, write papers, etc... I used it to calm my nerves about how much crap I have left to do in my Design Course... It is nice to break everything down sometimes. Finally, you can export your map directly from the iPad into PDF format and an outline format.
