>>I don't even see what the Kobo value prop is. It is not amazon encumbered. That is a huge value to many
I had three readers from Sony (until they exited the business) and one from B&N (until they exited the business), because I didn't want to deal with conversion. Of these still in the business, Amazon looks the least-like to exit soon, and now there's no need to deal with conversion. As most of the books I read are out of copyright anyway, I'm not "encumbering" myself with Amazon in any way, except for buying hardware…
Did they exit the business? It looks like the Nook Glowlight 4 was released less than a year ago.
I don't know a single person in real life with an e-reader other than a Kindle, including myself, so I had to google to see how B&N Nook was doing when you said that, but it still seems to be a thing.
