Ubuntu Desktop not used in business

I got a telling reponse from Canonical when I approached its Public Relations team looking for case studies of businesses that had switched from Windows:

… we find that the businesses using Ubuntu tend to use the server edition right now and so a windows comparison is not relevant. Ubuntu desktop is largely in the consumer space not business.

It hardly comes as a surprise to discover that most businesses use Windows, but I did think there would be a few examples.
