First of all, sorry for the late reply! My research before purchasing left me with the distinct impression that both major vendors (Amazon Kindle & Rakuten Kobo) make very good hardware that will serve one's needs. I did not want to purchase an Android tablet (e.g. Boox, even ignoring their GPL issues) as I found that concept to be too distracting/straying from the purpose. I chose to purchase a Rakuten Kobo Libra H2O, which is pretty good for my uses. I imagine the equivalent (but higher priced) Kindle Oasis to be as good or better. I went with the Kobo with the idea that I'd rather competition in this space not shrink further (though I doubt my actions matter much).
