Microsoft’s Windows phone is a complete flop. So Microsoft has to fall back on Windows 10 for the Microsoft Store. They have nothing else. They have to kill off Windows 7 in order to up sell with Windows 10 and the Microsoft Store.It's actually a fantastic product, and I know many people that tried it out and prefer it over the alternatives. From a market share perspective, it is indeed a "complete flop".
My wife loves her Nokia Lumia 635. Worth much more than the $40 it cost. It’s real quality. But it has little or no apps. Because hardly anyone uses one, businesses like banks are not releasing Windows phone apps. The Windows phone is a distant 3rd behind IOS ans Android. The Windows phone is DOA.
