As noted elsewhere in the thread, they do support MTP transport, so it’s definitely not as user-hostile as it first sounded. Things like Calibre will still work. However, the fact that Amazon also removed the ability to download ebooks in the browser for offline transfer suggests where things are heading. IIRC kobos have some anti features of their own, but I don’t recall the details. I wonder if something like the Daylight DC-1 could be even better. It’s not just a nice reader, but a proper computer. At least, if it actually exists.
