75% of my non-techie relatives who have retired from office jobs in the past 15 years - from workplaces where using MS Windows, Office, etc., etc. was required every working hour - have downsized to having only a iPad and iPhone. And they're completely happy that they did so.

They mostly just want a web browser and e-mail. They buy ~zero non-free apps. And they want the "freedom" you're selling about as much as they want the "authenticity" of living off the land in rural Alaska.
