At CES 2014, we saw a limited introduction of tablets that run both Android and Windows on Intel "Bay Trail" chip. Although the convenience of these devices is inarguable, the business part behind them is rather cumbersome and their future is disputable.
According to a DigiTimes, Google has "pressured" ASUS to "postpone" its plans to release its Transformer Book Duet TD300 hybrid tablet. The device which runs Android and Windows 8.1 could result in an increased penetration rate for Windows, which would benefit Intel and Microsoft, but not Google. It appears there's no way for ASUS to please all its partners at once with the launch of a dual-OS device, so the Taiwanese maker might have left the concept for better days.
Although Google and Microsoft's notable mutual disdain would suggest otherwise, the latter's recent expansion strategy openly relies on Android to bring Windows to mobile platforms. Since last year, there have been rumors of Microsoft asking its partners to produce dual-booting smartphones. The same happened with other types on devices, and at this year's MWC, Microsoft and Nokia launched an Android-based series of smartphones which serves as an introduction to Windows Phone more than anything.
It's understandable that Google wants to avoid Android becoming a vessel for a competing platform's success. Given that, it's likely that other manufacturers will also have Mountain View "nicely" ask them to reconsider their dual-OS plans. If that's really the case, that is.
