Sony has detailed an incoming update to its existing Reader Library software, which will soon be known as Reader Desktop Edition (for OS X and Windows). There is also word that a Reader Mobile Edition app is coming soon for Apple iPhone and Google Android-based smartphones, enabling users to synchronize their reading among multiple devices. This is most certainly a response to Apple’s iBook and Amazon’s Kindle app which has proven to be a popular strategy for those companies. These free Sony applications, available later this year, will offer an intuitive digital reading experience with an elegant interface and access to Sony’s Reader Store for browsing and purchasing content. Reader Desktop Edition also includes the ability to easily manage content for the non-wireless Reader models.
