Pros
Pro It is easy to transfer notes to OneNote
OneNote offers quick and easy transfer software in order to import from other services.
Pro Offers flexible encryption
Unlike most other apps, you can selectively password protect, and fully encrypt, individual documents or entire folders. This is especially important to many people with data stored in the cloud. As of early this year, even the free version supports encryption. Microsoft has also enhanced their internal security methods for storing data on OneDrive (where OneNote performs sync), which makes it more secure than most of their competitors (including Evernote).
Cons
Con You cannot use local OneNote files with the version of OneNote that is included with Windows
There is a difference between the OneNote that is included with Windows 10 and the OneNote that comes with Microsoft Office. The version included with Windows cannot use local OneNote files and requires you to be online to access your notes.
See here for this and other differences.
Con No way to generate a list of actions or flagged items from the notes
If you are keeping notes from various parts of you day in OneNote and keep writing list of things that you need to do - e.g., list of grocery items, homework assignments, books or movies to check out and errands to run, these are scattered across different pages. Even if these are tagged with different tags there is no way to filter all the actions (in one notebook section or entire notebook or across notebooks) that have a certain tag.
Con Limited storage
Every user receives 5GB of cloud storage through OneDrive (it used to be 15GB). This can be limiting, especially if OneDrive is being used to store other files as well. Add a few videos into the mix inside of a note and it will be easy to max out this storage quickly. More storage of course can be purchased, but may be too costly for some.
Con No good way to print (paper, PDF, or any other neutral file format)
OneNote pages are semi-infinite (like excel) and great for taking notes in the application, however there is no Page Break view (unlike excel), or any other good way to export your note to someone not using OneNote (ie. teachers, colleagues, supervisors, etc). Neutral file formats exist for a very good reason, and OneNote does not have a professional way to do this (because it comes out as an uncontrollable garbled mess).
