Has it become apparent to them yet that they should have bet the farm on their mobile effort? Pure more resources into improving it, rather than gutting it. Change the branding even. Windows branding is associated with desktop operating system and will always be. Not cool personal, mobile consumer electronics devices and gadgets.
Now I am reading Microsoft is pushing Windows as a competitor to the Echo. And home automation. With the differentiator being full Windows? The desktop PC market (full Windows) is not the same market as consumer electronic/gadget market in which devices like the Echo falls into.
No one's buying an Echo is complaining it doesn't run full Windows.
