Is there any good answer to the question of why Microsoft is so focused on marketing a Miracast device with its very limited functionality, i.e. mirror screen, as opposed to the versatility of Apple TV or airport express? I am particularly interested in the music streaming capability of apples airplay feature, which allows music and video streaming from any IOS device to the receiving unit. Why is dlna not available on Windows phone? Am I the only one using my phone or tablet to stream music to my stereo? I own several Windows phone and a Surface pro 3, but still I have an iPad lying around for listening to music on my stereo. Any good solutions for my usage scenario?
