Microsoft had/have an excellent mobile OS and Windows phones available and was gaining traction. All the promise of UWP and integration between W10 and the Band and WP and Xbox and so on disappeared under Satya, not Ballmer. The Band is the most bizarre deprecation for me, seeing as there's still nothing on the market which does everything it did.
