Is the Justice Department really serious about this? >From CNN's website. Robber barons? The government fired back at Microsoft, with Attorney General Janet Reno emphasizing the Justice Department's determination to create a fair market and competition among U.S. businesses. "America was not made the industrial giant of the world by the robber barons alone," Reno told her weekly press conference. "It was made the industrial giant of the world by competition, by encouraging new developments, by encouraging young entrepreneurs to break into the market. It's the best system I've seen so far." In view of Microsoft's monopoly with the Windows operating system, Reno was asked why the Justice Department has bought tens of thousands of PCs running Windows, rather than buying alternative operating systems. She replied that monopolies limit choice, "I don't think you endorse something by purchasing it," Reno said, "if that's the only game in town...in terms of an effective machine, the lowest price available."
