p4One of Asustek’s big announcements at CES this year was the creation of the Transformer Book Duet TD300: a tablet that could turn into a laptop, and run both Windows 8.1 and Android.

Now, it seems like the dual OS dream is dead.

While Taiwan-based Asustek (better known in the U.S. as Asus) wanted to forge ahead with the project, both Microsoft and Google opposed it, according to a report by the Wall Street Journal. Even though Android is open-source, and any company can create their own fork of the operating system, Google still has the final say about whether a version of Android can use the company’s Play store, and its other apps like Google Maps and Gmail.

The Transformer Book Duet was Asus’s response to a continually shrinking PC market. While analysts have predicted that sales of personal computers will eventually stop declining, it’s clear traditional PC OEMs will need to find new products. Asus’s new offering was supposed to offer consumers the best of both worlds: an Android tablet that would allow users access to a broad mobile app ecosystem, as well as a Windows device that would allow people to use Office and other apps that haven’t made their way onto Google’s platform.

Its hardware was supposed to offer similar opportunities: users could detach the device’s screen from its keyboard and use it solely as a tablet, or attach the keyboard and use it like a laptop.

However, it seems like Microsoft and Google felt they were getting the raw end of the deal. According to the report, Microsoft didn’t want to let Google get a potential foothold in the enterprise market, which is the core of Microsoft’s power base. Meanwhile, Google has shown that it only wants to support devices that conform to its expectations of what Android should be.

When asked about the report, a Microsoft spokesperson told GeekWire via email that the company’s policies towards OEMs haven’t changed, and that “Microsoft will continue to invest with OEMs to promote best in class OEM and Microsoft experiences to our joint customers.”

Asus and Google did not respond to requests for comment on this report.
