Are you wanting to sync with your NC? If the STR doesn't then I doubt any other eInk readers will. The only ePub app I know of that autosyncs bookmarks, notes, and highlights is iBooks and it isn't available on eInk readers. Sony readers sort of sync between each other but not as well or easily as Kindles, but they won't sync with other devices unless the Sony for Android app supports syncing, and that app is pretty lackluster. I hope I'm wrong as I've searched high and low for a way to autosync with tablets and eInk but to no avail.
