      Google Play Books vs calibre opinions
      Some users think Google Play Books is a great alternative to calibre, some don't.
      Allows epub-format books to be uploaded, at which point they become available on all devices you have GPB installed on. I use this for all my public-domain (Gutenberg, Azora-bunko, etc) ebook reading.
