The One Laptop Per Child Project and Microsoft plan to make both Windows and Linux available on a version of the project's XO Laptop. It means the little green laptop would now run Windows XP as well as Linux. According to Nicholas Negroponte:
OLPC is not in the open-source advocacy business ... we're in the education business.
This will not just kill enthusiasm for the project but the project itself. Windows XP will not run smoothly on low end hardware. It will be now dual-boot system with Sugar and Microsoft's Student Innovation Suite, a US$3 software (Windows XP, Microsoft Office Home and Student 2007, Microsoft Math 3.0, Learning Essentials 2.0 for Microsoft Office and Windows Live Mail software).

OLPC did not specify the price of the dual-boot system.
