This disregards the benefit of a single device that is easy to carry. Love where this is come from so maybe do both if you can.

It's a trade-off. I love the convenience of ebooks, but not owning my books is just categorically unacceptable to me. I want my daughter and anyone else coming after me to have free access to them, not to have to jump through Amazon's hoops (if such hoops even exist) for access.

I have a Kobo that I use to read the non-DRM ebooks I'm able to acquire. One such source is downloads from the Kobo store, when publishers make the non-DRM file available.

I use a kindle but I have never bought a book on the kindle store ever (been using it for 10 years). Totally doable and not hard to avoid... especially since the smaller stores not only have better sales but the author typically gets more money too.
