jbrodkin writes "Microsoft CEO Steve Ballmer used the official state visit of Chinese President Hu Jintao as an opportunity to complain that 90% of Microsoft software users in China didn't pay for the products. The comments were part of a discussion with Barack Obama and the Chinese president about intellectual property protection. According to a White House transcript, Obama said in a press conference that 'we were just in a meeting with business leaders, and Steve Ballmer of Microsoft pointed out that their estimate is that only 1 customer in every 10 of their products is actually paying for it in China.' Obama didn't detail any specific measures the US and China would take to help Microsoft and other vendors fighting software piracy. 'The Chinese government has, to its credit, taken steps to better enforce intellectual property,' Obama said. 'We've got further agreement as a consequence of this state visit. And I think President Hu would acknowledge that more needs to be done.' Microsoft did not say how it calculated the statistic that 90% of Chinese users aren't paying for Microsoft software."
