I'm considering upgrading my main mac to El Capitan...just because . I do use the Notes app a lot and have several other apple devices. Does anyone know if I stay away from the special formatting and other features of the El Capitan Notes app will the El Capitan Notes iCloud sync with my other devices...iPhone and iPad running IOS 8.4.1? Also, any feedback on the performance or battery life of the El Capitan beta's welcome. I have a late 2014 Macbook Pro 13".
