I bought a book with Adobe DRM once. It was a relatively obscure book, and I wanted to support the author. Downloaded the file. Installed Adobe ebook software. Then something went wrong. I had to uninstall and reinstall Adobe software, and after that I couldn't open my new book anymore. Had to break the DRM. I never bought any other e-book with Adobe DRM again. It was obvious that the user experience was the last thing Adobe cared about. I also avoid Google Play Books. E-books are just one of too many things Google does. IMO Google won't think twice before switching off the service. I do buy some Kindle titles though. At least it works, books are linked to my Amazon account, and Kindle is core business for Amazon. I bet it will stay around longer.
