Ballmer repeats threats against Linux

Steve Ballmer has reissued Microsoft's patent threat against Linux, warning open-source vendors that they must respect his company's intellectual property.

In a no-nonsense presentation to New York financial analysts last Thursday, Microsoft's chief executive said the company's partnership with Novell, which it signed in November 2006, "demonstrated clearly the value of intellectual property, even in the open-source world."
