U.N. Secretary-General Kofi Annan and U.S. researchers have unveiled a $100 laptop computer intended for millions of school children in developing countries.

Mr. Annan and members of the Massachusetts Institute of Technology (MIT) showed off the low-cost machine Wednesday at a U.N. technology summit in Tunisia.

They expressed hope that governments and charity groups will pay for the laptops, set for distribution beginning next year.

Developers from MIT created the green-and-yellow computer to operate by hand-crank when electricity is unavailable, and to access wireless networks.

Earlier, negotiators at the summit agreed to allow the United States to continue managing the domain system that guides traffic on the Internet. The deal also calls for a new forum to give other governments a stronger voice in making Internet policy.
