MobileNoter SE 1.1 has an integrated Dropbox sync functionality. It doesn't require installing the Windows Sync Client or any additional tools, loading notebooks via USB connection or any other actions on your side.
All you need to do is to store your notes in Dropbox and to log into your Dropbox account in the MobileNoter application. After this you'll be able to sync your notes in one touch and you can do it anywhere and at any moment. This is the fastest and most convenient way to synchronize your Android device with Microsoft OneNote. Synchronization has never been that easy!

UPDATE: MobileNoter SE for iOS is planned to be released in Q3 2011. Most probably it will be sold through the App Store (no PayPal, finally).
