Started playing with OneNote.
In a nustshell would be describe this as effectively a document managment system?
Instead of saving in folders and such, one uses notebooks.
Advantage seems to be ability to share etc, and keep all relevant stuff together, be it sound, images etc.
Would this efefctivley replace box/dropbox for a person. All documents can be on cloud and desktop, plus sharing and collaberating is possible.
