In contrast, the HDD-equipped Xbox 360 has a manufacturing and materials total of $323.30, based on an updated estimate using costs in the fourth quarter of 2006. This total is $75.70 less than the $399 suggested retail price of the Xbox 360.
What's making Microsoft lose money are NOT the Xbox 360s themselves, it's the marketing, warranty replacment, new advertisments etc. Their cost will never turn into a profit, though as neccessary as they are. The Zune didn't help either, it's hard to make a new piece of hardware without a loss around launch. Plus, the costs of Vista and Office 2007... the list goes on. But for anyone to say that the 360s are so damn expensive is very naive at this point.
