Q:

Google Analytics just start tracking Windows Phone as an OS?

Just wondering if anyone else has dug into the Windows Phone traffic they have in Google Analytics?  
The graph below describes it better than I can.  The timeline is showing the last year, and we have nothing before November.  

Did Google just incorporate/recognize this lately?
Our tags haven't changed.  
The other thing I notice is that if you check out the version, there are only visitors from 7.0 and 7.5.  Does Google only track 7.0 onwards, or can I find stats on earlier devices (i.e. Windows Phone 6.5, Windows Mobile 6.1 devices, etc...) somewhere else?  I would really prefer not to have to look by screen resolution, as that's a mess of information to look at.
Thanks in advance for any anecdotes/comments/answers people might be able to provide.

A:

Previous versions of the operating system on "windows" phones are under Windows, which on my analytics has subtypes CE and ME. What I don't know is how those subtypes map to the different versions of Windows CE. The wikipedia article on Windows CE says

Windows Mobile is best described as a subset of platforms based on a
  Windows CE underpinning.
