The MS Word Notebook format is not bad. I tried it, but it is still not OneNote. As mentioned above, do give a Notebook from Circus Ponies a try. The Evernote is also great for taking/organizing notes, but it does not have the features of the Notebook. Hopefully Evernote will continue to further develop their application (as they have so far). Right now I use both the Evernote and the Notebook.
