I would like to see a phone case which this inserts into --- bonus points if there's a way to use it as a status display for the phone for use in bright/direct sunlight.

The obvious innovation is to just make the back of the phone case an eInk display. No need for all the bulk when you can merely have an app on your phone that controls the case-display and the phone can output whatever reader app you want to it like a companion/IoT device.

Or it can be a little bit bulkier and just be a dedicated ereader that is shaped like a phone case. Either way works.

The phone case idea would be nice, but then the device has to be replaced when the phone is replaced.

Yeah but I’ve seen color e-ink fridge magnets that are like $30. I don’t think it ends up being more expensive or substantially worse for the environment than people buying cases made of fancy leather. Presumably the display module could also be cut out of it for DIY uses.

So, Yota phone?

Can someone explain the whole thing about wanting to attach it to your phone? Why? What does this provide over just putting it in your pocket?

I'll never forget it. It's always on the back of my phone, so even if I'm in a hurry and run out I can still read a book on the metro.
