In upcoming versions, you’ll be able to add drawings and images into your notes. $4.99
Audiotorium – http://audiotoriumapp.com/ - This app will allow you to create audio into your notes. You can also share your notes with friends. (As of this writing, Audiotorium is not available in the App Store so I don’t know the price. This site has some photos of it.
