There needs to be a unified solution to ebooks. With a regular paper book, I can take it anywhere and read it with no limits on where I purchased it or how. With a Kindle or Nook, I can’t read books purchased from Apple Books. With an iPad, I can read Kindle or Nook, but only from their respective apps. Each app has their own interface to lure you into their ecosystems. I can import certain formats, but usually lose features reserved for only proprietary ebook formats. I think it is a mess. I really need one central book case, like I have in my living room, not a bunch of different digital safes to store competitor’s proprietary restrictions on words.
