And that was just one of a number of highly embarrassing verbal contortions played for the benefit of the federal courthouse Monday. Confronted with one of his own mails in which he describes enhanced "browser share" as Microsoft's "No. 1 mission," Gates shot back: "We didn't mean browser share, we meant browser usage." Bill Clinton would be proud. Clinton, of course, didn't have to face a single judge with arbitrary power. Thomas Penfield Jackson, the man who will determine Microsoft's fate, was spotted chuckling and shaking his head as Gates tied himself in knots trying not to use the word "Netscape." It doesn't look good for the defendants - and there are still 19 hours of the Gates tape left to run.
