Notes is a big, lumbering beast. It's only used by big orgs that can afford big training programs. And once they've trained everyone, they've minted a new generation of users who believe that that's how computers work. Every new thing requires extensive training because it's just sooooooo complicated.
Tell someone in that category that this new thing won't take any training because it's so much simpler, and they just assume it's not doing something that they need. They don't know what that might be, but there's got to be something it's leaving out.
