>Perhaps the US govt is being so cautious about breaking up Microsoft
Cautious? With Judge Jackson comparing them yesterday to the Rockefeller Standard Oil monopoly? With the Justice Department and several states having brought the suit in the first place? I don't know that I'd call that cautious.
Your claim of U.S. industrial superiority - and I'd agree it's pretty superior in the computer field, broadly defined - depends on the power to innovate rapidly and keep competitors off guard. Microsoft is anything but an innovator - it wants to retard innovation, like GM or US Steel in the 1950s.
