Bill Gates, who is obviously an expert on every subject under the Sun, has made a mockery of the $100 laptop computer for developing countries, currently being developed by the Massachusetts Institute of Technology with the backing of Google. The laptops lack many features found in modern computers, such as a hard disk and software.

Gates said at the Microsoft Government Leaders Forum in Washington, DC: "The last thing you want to do for a shared use computer is have it be something without a disk... and with a tiny little screen."

He said, "Hardware is a small part of the cost" of providing computing capabilities, adding that the big costs come from network connectivity, applications and support.
