I'm not a paid user of Evernote, so perhaps I don't matter, but I am a daily user, and I only use the first bullet point listed here -- native applications on three different operating systems. I don't use any of the advanced features of Evernote and I don't even use multiple notebooks. That is to say, an open-source Evernote competitor won't be able to meet the needs of 100% of Evernote's users, but it will be able to capture some fraction of those users. I'm personally very interested in an open-source Evernote that I can run on my own server.
