Often, I will take notes either for a meeting or for sharing ideas. I will pass these around (different companies and possibly timezones) My recipients like receiving an email they can read without having to follow a link set up an account etc. Business users tend to just keep emails form people as a "file" copy. Incidentally some of my recipients liked what they received and this led them to get Evernote accounts as this feature was valued by them also as it meant they could keep notes in one place but share easily without any expectation placed on the recipient. I feel onenote is an inferior product but will be easier platform to share notes etc. This feature was kind of the key to making the most of evernote. Hopefully this helps
