Leopard Beats Vista for Corporate Satisfaction

http://www.pcworld.com/businesscenter/article/143960/leopard_beats_vista_for_corporate_satisfaction.html

While these articles might say that one beats the other, it doesn't say what kinds of competitive advantages or competencies that these companies are looking for in these two products nor whether these two companies have used both operating systems before. Statistics is not a very powerful form of evidence if it doesn't have the reasons, assumptions made into collecting the data, or the methodologies for collecting the data. To me, I would read this article with skepticism.
