I appreciate the aesthetic of flat bezels, but I find cases more annoying than bezels so I go for bezels to avoid needing to buy a new reader every 6 months to a year. My flat-bezeled Onyx Boox and Pocketbook readers have proven much more fragile than my fully-bezeled Kobos and old Kindle.

I have not had enough luck busting Kindle books out of drm for the last few years and assumed Kindles were out of consideration.
