Windows Phones sell a whopping 12.375m+ units in Q4 2012?

I think that's a bit too high. Most likely Balmer was speaking of one specific type of phone w/ WP, not as a whole. If it was for WPs overall, and they were truly selling 450% up YOY, MS would have stated as much, as well as given sales numbers. Probably still an improvement, though.
