I'm looking for a dumb phone and this looked promising until no email. Email is underrated as a time saver, if you aren't getting hundreds of emails daily which is a choice. Email is not as urgent as text or phone calls and its main advantage is that it separates the sender/receiver schedule or timezone.
People need to learn to guard their time and schedule like a hawk and not operate in chronic reaction mode, i.e. someone else setting your priorities for the day.
