Almost all mainstream e-readers and computer operating systems support the format, but publishers can also wrap it in any DRM system of their choosing (although you can remove the DRM on any ebook you own).Īnd the downside? Amazon Kindle devices cannot read it (except for the Kindle Fire tablet). In many ways, it's the ebook equivalent of the trusty MP3-both in a good and bad way.
