One note is a great program to take notes. If you have a PC, Ipad or MAC you can add information to your Notepads and synchronized it across devices. Now you can email your notes to firstname.lastname@example.org and they will automatically appear in your notes.
This was the big differentiator between Evernote and OneNote but not anymore. No need to pay for Evernote any more.
