Microsoft revealed more about Continuum, one of the big new features of Windows 10 Mobile. Continuum enables you to use your Windows 10 Mobile smartphone like a PC, by connecting it to a big screen and a (Bluetooth) mouse and keyboard. As Windows Central reports, this enables you to use the phone as a Windows 10 PC, while still using all of its phone features.
The video also shows how Windows 10 Mobile can connect wirelessly to a big screen TV, via the Microsoft Wireless Display Adapter, without the need for a Display Dock.
Pretty impressive stuff, but I doubt this will be able to resurrect the Windows Phone platform.
