I'll look into Libreofficee and Collabra Office. I definitely use OneNote a lot...primarily for common shopping lists, tennis drills, racquet recommendations, etc to share with my wife. One thing I never liked about iOS Notes is lack of formatting w/bulleted and check lists, colors/fonts, etc.

Wonder if the two you mention cover some of those features - or if I need to see how far along Evernote has come...and their own potential invasions of privacy. And does anyone know if Apple does the same thing if using iCloud, Notes, Mail...which by the way, I really can't stand Mail, but that is because I've used Outlook for decades?
