Xoj,
You are totally ingnoring that the Windows Mobile platform had 1 profitable year (2 million dollars) and that was year the 360 was released. Since then Windows Mobile has been under assault and has been loosing money and was then put on the EDD division around the same time the iPhone was introduced and started taking big chunks of marketshare.
This quarter the 360 will have awesome profits. Profitable hardware, very profitable accessories, profitable software, and profitable Xbox live.
Its libraries that sell systems not a single game.
