This piece seems to imply that only full source compatibility with Android (including Play Services) would be valuable to the Windows Phone platform. I don't think that's the case.

I think a more interesting question is whether Microsoft should fork AOSP as a whole, or place an Android compatibility layer atop Windows Phone, a la BlackBerry 10.
