hweimer writes "A novel study analyzes the installed base of various office packages among German users. (Here is the original study report in German and a Google translation.) While Microsoft Office comes out top (72%), open source rival OpenOffice is already installed on 21.5% of all PCs and growing. The authors use a clever method to determine the installed office suites of millions of web users: they look for the availability of characteristic fonts being shipped with the various suites. What surprised me the most is that they found hardly any difference in the numbers for home and business users."
