I only use eInk to read at the beach or pool. I am still happily using a Kindle 3G. That’s an old, old model, but it still works and it has physical page turn buttons. Too old to work with the Kindle store even over WiFi. But sideloading works just fine, and I always have a laptop on vacation. As long as I have 3-4 books ready each day I’ll never be caught short. Download, strip DRM if desired, sideload.

Now I suppose it will just be Anna and me doing the sideload.
