Check this if you want to really know what kind of money MS makes and where it comes from. The Xbox is part of the Home Entertainment division. That division is nothing compared to their others.

Fourth Quarter
Home and Entertainment revenue increased primarily reflecting an increase in Xbox revenue of $503 million or 129%. Xbox revenue increased mainly due to the shipment of 1.8 million Xbox 360 consoles, which exceeded the number of first generation consoles sold in the same period of the prior year. In addition, Xbox 360 consoles sell at a higher average price than first generation consoles. In the fourth quarter of fiscal 2006, the availability of Xbox 360 consoles was no longer limited by supply constraints. Growth in revenue of $48 million or 24% from our Home Products Division, TV platform products, and PC games sales also contributed to the total Home and Entertainment revenue growth.
Home and Entertainment operating loss increased primarily as a result of a $682 million increase in cost of revenue primarily associated with the Xbox 360, partially offset by the revenue growth. Our business model anticipates that while we currently sell Xbox 360 consoles at a negative margin, product cost reductions and the future margins on sales of games and other products will enable us to achieve a positive margin over the Xbox 360 console lifecycle. The first generation Xbox consoles continue to have negative margins. Headcount-related costs increased 11% reflecting both a 19% increase in headcount and an increase in salaries and benefits for existing headcount, partially offset by a decrease in stock-based compensation expense.
