I get Jonathan Schwartz' complaint about the default use of Windows by so many organizations - both public and private. On the other hand, I can deal with Word docs on my Mac without a problem, and my Mac also handles Windows Media player files just fine. Interestingly enough, my Mac is a better citizen on my local LAN (from a Windows file sharing perspective) than the other machines are; one of my wife's machines sometimes just disappears from the LAN without losing connectivity otherwise. Go figure.
I suppose I should get to the ironic part - Schwartz is out advocating for the ODF format. Meanwhile, Corel just backed away from ODF in WordPerfect (reported by ComputerWorld this week). If Microsoft wants to really put egg on the face of the ODF backers, they'll ship support for the format in Office 12. Now that would be amusing.
