2nd graph is pointless. It has nothing to do with Xbox or Xbox Live.
Xbox 360 and Xbox Live are in E&D
The E&D division is mainly Zune, Windows Mobile and Xbox (Live). There are things like office for Macs and headsets or keyboards, but those are tiny compared to the first three.
Zune is basically losing money since its introduction in 2006. Windows Mobile will see a massive and promising update soon with the release of WinMo 7. Until then it keeps on losing money and sucking R&D costs for WinMo 7. The division reports profits for every quarter since January 2008. How can this be the case? That is because of the Xbox 360 and Xbox Live. The Xbox 360 will break even very soon and make a nice little profit in the end. Sure the profit might not be as gigantic as the other divisions will report, but that is a comparison nobody in this industry could really win.
