Earlier we challenged Moore's Law with OpenOffice.org. Today we have a three-way match. In the first corner, we have heavyweight Microsoft Office; in the second, undefeated champion Moore's Law; in the third corner, underdog OpenOffice.org. Let's get ready to rumble!
Again we are measuring the installed disk usage of each release. Because old versions of Microsoft Office are not as accessible as OpenOffice.org, the sizes are based on system requirements printed at the microsoft.com web site—a site which is remarkably thorough. Another complication is Office's numerous editions. The number of editions has ballooned from a 2 in Office 4 (1994) to a confusing 9 in 2007. While all editions have Word, each edition has a different set of other products such as Access, Outlook, and Visio. Which should be measured? I used the printed values for the typical installation size for the Standard versions. Release dates are courtesy of Wikipedia.
