Sorry for chiming in on an old post, but speaking of OneNote, Encryption and Privacy... I signed up and throughly played with OneNote just for a comparison about a year ago. I even migrated some content over... Not longer after, to my surprise/ chagrin I received an email from Microsoft stating that my account was locked due to some potentially 'harmful' content in my account. There was no option to retrieve the content, mainly some ebooks and a few notes. This became the biggest deterrent to dealing with Microsoft for my private notes. Yea there's no encryption yet in EN (I truly believe it's coming), but at least they aren't snooping in my stuff. I don't know what could have been 'harmful' and I don't care, I value freedom, or at least a greater level of freedom than OneNote.
