MSFT has historically had a REALLY hard time doing anything objectively good and successful in mobile. It's amazing to me, given their resources. I think, in the Ballmer years, what hurt them was his ideological obsession with Windows Everywhere -- like, down to the Start button. I'm still pretty convinced that mobile needs a fundamentally different interface than desktop, and not coincidentally that's the way Apple has approached it. MSFT under Nadella is way better in lots of ways, but they still seem to think Windows oughta be the way for every device, and it hurts them.
