[8] The interchangeability of Android and Windows, coupled with the ability to switch between tablet and ultrabook form-factors have led some news sources to call the Transformer Book Duet a "four-in-one device".
[12] Since its announcement at the Consumer Electronics Show on January 6, 2014,[2] the Transformer Book Duet has received a high degree of media attention from technology magazines and other mainstream news sources.
"[13] Joel Santo Domingo of PC Magazine said that the Transformer Book Duet is helpful for any consumer or business-person who needs to use both operating systems.
[4] In March 2014, The Wall Street Journal reported that because Microsoft and Google had both implemented policies which effectively ban the certification of devices which dual-boot both Android and Windows, the Transformer Book Duet would be cancelled, and Asus would pull its similar all-in-one desktops from the market.
Additionally, even though Android is an open source operating system that is freely available, Google's application suite is proprietary, and can only be licensed for devices which are approved by the company.
