cc writes "The Des Moines Register is reporting that opening statements have started in the Microsoft-Iowa antitrust case. The Des Register reports that the Plaintiffs have shaped their case around nine stories involving competitors from IBM to Linux. Microsoft attorneys say Gates is expected to testify in January, and company CEO Steve Ballmer will likely appear in February. Both men are expected to be on the stand for about four days. Unlike previous antitrust cases against the software giant, the Iowa case is seeking additional damages for security vulnerabilities. Plaintiffs allege that Microsoft's bundling of IE with Windows caused harm to consumers by increasing the consumer's susceptibility to security breaches and bugs. The case is one of the largest antitrust cases in history, encompassing millions of documents and Microsoft's business practices during the last 20 years."
