You no longer have to have lots of notes scattered in different files, paper pads, and other locations. Just jot down your thoughts as they occur to you and keep them in one place with OneNote.
OneNote allows you to toss ideas onto a page in an unstructured way. You can go back later and add the structure you want or completely rearrange the notes in a different order. It's a great way to take notes.
