The Barnes and Noble Nook Glowlight Plus came out a few weeks ago and many users are reporting that it is not compatible with Adobe Digital Editions. This will prevent you from borrowing e-books from the public library or shopping at other bookstores.
Barnes and Noble technical support has been aware of this problem since before the Glowlight Plus even came out. When asked for comment on why it was incompatible with Adobe Digital Editions they simply said it was due to “improvements they have made.”
I think the improvements they are referring to is basically just insuring that people are not buying digital books outside the Nook e-book store and loading them onto their device. The first stage of this new philosophy took place in September of 2014 when Barnes and Noble disabled the ability to backup your purchases, because they did not want people removing or striping the DRM.
If you are thinking about buying the new e-reader from Barnes and Noble and borrowing e-books from your local library, I would recommend against it.
