To me the interesting part of an e-ink frame is that it wouldn't require any battery/cables (otherwise you might as well just get a regular digital frame)

I would love if there were a product where you just program the frame with a picture once by plugging it into your phone and using an app

Then you never worry about batteries/cables and you can always change the image later

To me that is the killer app

At that point, why not print a few photos, put one in an easy to change photo frame, and spend a couple minutes swapping them out now and then?

My brother tried to get my dad setup with Apple Music which he spent an afternoon frustrated with. OK, the UI isn't the best but I'm not sure anyone else's is better. I ended up getting him a desktop CD player, gave him a bunch of CDs I don't need any longer, and he's very happy. Sometimes the old (OK not quite) analog approaches are better.

ADDED: My (younger) brother rolled his eyes a bit and was a bit surprised CDs even existed any longer but sometimes simpler approaches really are better. And I'm the one with engineering degrees :-)
