We've seen numerous companies announce devices that boot Android and some flavor of Windows, but very few of them ever hit the market. Just yesterday, Huawei announced that it was switching its Windows Phones to dual-OS Windows Phone/Android devices, which would launch in the second quarter of this year. Samsung announced the Ativ Q dual-boot convertible nine months ago, and we never heard about it again. One of the few companies actually shipping dual-boot hardware is Asus, which offers a convertible tablet/laptop and a few all-in-one PCs.
According to a report from The Wall Street Journal, Microsoft and Google are both out to stifle any device that doesn't have a firm allegiance to either Android or Windows. The report says that both companies have told Asus to end its dual-OS product lines and that Asus is complying. The WSJ says Asus' newest dual-boot product, the Transformer Book Duet TD300, which we wrote about during CES 2014, will never see the light of day. Asus' all-in-one PCs, the Transformer AiO P1801 and P1802, will be pulled from the market.
Both companies have reasons to want to stop dual-boot devices. Windows 8 is under pressure with its desktop, and Microsoft does not want Android to get a foothold there. Android dominates smartphones, and Google doesn't want Windows Phone paired with Android. Both companies have ways of making OEMs comply with their wishes. Microsoft provides PC OEMs with marketing funds, which the report says are an "important economic force" in the low-margin PC business. Companies that aren't on board with Microsoft's vision could have their money dry up. While the base of Android is open source, the Play Store, Google Maps, and other Google apps needed to make a viable smartphone are under Google's control. Companies that don't comply with Google's requests might not get the apps they need to have a competitive product.
