Summary: In recent weeks Microsoft has been doing some odd things with mobile operating systems, Windows RT, and Windows Phone 8. I think Microsoft is moving towards dropping its mobile OSs in favor of supporting Microsoft applications on other platforms and eventually replacing them with Windows 8.1 on their own devices.

This is not your dad's Microsoft. Microsoft has been refocusing on Web services and devices instead of Windows and software products. One of those changes seems to be that if Microsoft's mobile operating systems can't cut the mustard, Microsoft isn't afraid to cut them off at the knees.

What am I talking about? Let's look at some of Microsoft's mobile news in the last few weeks.

First, some background. Goodness knows Windows 8 has been a market failure, but it's a rip-roaring success compared to Windows RT and Windows Phone 8 (WP8).
