Microsoft was never in a prime position to succeed in Mobile. I'm not sure why you think this, but it's probably related to their European market share numbers that placed them close to iOS market share numbers in certain markets. What people, that use these insignificant metrics, fail to realize is that these market share numbers were composed of cheap devices that had very little, if any, margin. In fact, Microsoft was probably losing money by selling all of those cheap devices for less than what it cost to make them. Microsoft lost Billions in mobile and never were able to gain any traction with their platform. There comes a time when you need to stop the bleeding and move on. Only a fool would continue pumping resources and money into a venture which has never returned a profit or market share.
