Rich people have the same number of seconds per day as poor people, except each second is worth more. Right now everyone is driving a black Model-T; there isn't a premium edition of email available, though one is certainly desired (personal assistants and secretaries currently fill this gap).
If the cost of a premium email/task-list system is less than the dollars saved in time, and less than an assistant, people will buy it. Aim for the higher-end market, solve their problems first on their dollar, and later expand downward to everyone else.

I think you misunderstand. The premium edition of email is much like the premium edition of anything else- it's the email you don't have to use, the plane you don't have to fly, the car you don't have to drive, the food you don't have to cook. So I don't know that personal assistants and secretaries are "filling a gap" in the stop-gap sense, but rather they are the solution.
If you want to capitalize on it, do like a chauffeur company would do, but with email.
