One cool move on Microsoft's part can be releasing Microsoft's version of Android. The main problem is Google Play Services. But since MS almost has parallel offerings for all Google Services they can create an "API" compatible version of Google Play services. This way users will be able to install all the current Android applications which are available on Play Store.
This can convert Android into an Oligopoly instead of Google's Monopoly.
