This is a silly question, but here it is anyways. How many devs does Microsoft have working exclusively on the Windows Phone OS and shared libraries? And how does that compare to say how many devs are working something of purportedly equal value, say XBox or even Excel? Or is dev count a stupid metric for assessing liveliness? 

I'm personally not going to touch it until there is a version of sql compact that runs on it. But hey, to each their own.
