This is something Evernote must truly become better.
Although Evernote is far superior than Onenote from collecting and organizing notes\information captured from the Internet, Onenote excels in formatting capabilities and so is much better for personal notes.
Onenote allows:
faster notes formatting, so we can be more productive, saving time and focusing in content capture.
personal notes be more readable, since are better formatted.
In my opinion, better formatting, with Styles included with Table of Contents of the note itself, will allow a true boost in Evernote to become even more appealing to existing and new users.
