Version 2 adds more consistent cross-platform display of notes, full-page view on iPad, and additional formatting options, among other smaller changes. Microsoft does suggest that current OneNote users sync their data before upgrading.
Today we are proud to announce the new versions of OneNote on iPad, iPhone and Android. Internally, we have been calling them version 2, and we think you are going love all of the new features and functionality available in these updates. A lot of the features are based on your feedback and we look forward to seeing what you have to say about this update.
