Microsoft doesn't give a 'sh1t' about competing with Android and Apple.

In fact, Microsoft doesn't care about the mobile phone business at all; they haven't turned a profit on their mobile products in 15 years, and they can jolly well spend the next 15 years doing the same.

What Microsoft does care about is the fact that Linux will eventually come to dominate the mobile phone ecosystems. This is an inevitable fact; it's only a matter of several years. Linux makes too much business and money sense not to win, and the success of Android shows how true this is.

Linux on the handset will greatly erode Microsoft's marketshare on the desktop, so it's understandable that Microsoft is doing all they can to delay the inevitable.
