On March 10, Microsoft and Nook Media updated their agreement forged two years ago, according to a new 8-K filing by Barnes & Noble. Under terms of the amendment, Nook Media is allowed to discontinue distributing the Nook Windows app and to cease work on its Windows Phone app. Ouch. There seemingly is a replacement app coming for the Nook Windows app, however. It’s rather confusingly named “Microsoft Consumer Reader.” This is not a dedicated e-reader, I hear from my sources. (Such a device from Microsoft has been rumored in the past.) Instead, I think this is just the name for one of Microsoft’s coming e-reading apps. There seem to be at least two of these apps in the works. The Microsoft Office Reader app, which company officials showed off last year at an employee meeting, will provide users with access to digital content, PDFs, and textbooks, according to leaks.
