Microsoft ran a Surface Event in New York City recently. Much to the surprise of many people they announced a new phone was coming in 2020. It is called the Surface Duo, not the tempting "Surface Phone" that almost everyone will write about.
Surface is a brand within the Microsoft ecosystem. It primarily targets business users with premium PCs and related hardware. It tends to use new device types. Devices that show how Microsoft believe hardware should be to take forward the ecosystem based on it's Windows operating system. It needs to carefully not be seen to directly compete with it's hardware partners. However, what it can do is stir their partners to make different device types by showcasing new designs under the Surface brand. You won't buy a Surface device as a budget item.
The big surprise for the event was that Microsoft would release a dual screen device running the Android operating system in late 2020. This device would be a phone.
Windowsphones running Windows 10 Mobile will end support in December 2019. Microsoft has decided if it wants to produce a phone then the phone must have the applications people expect. As a result it needs to be Android. There are plenty of good Android devices available so, in the spirit of the Surface mission, it needs to have a new form factor that is not being out out by other manufacturers. Therefore it is a dual screen Surface device running Android.
The new Microsoft. Going with what works.
