Sword, take the Army off of the list. They haven't used Macs for years now (they used to use Classic for web servers, with Webstar software). Add Richard Dreyfuss, who was called an "Apple Master" by knowledgeable users. Also, Stephen King has a PowerBook. Ana Marie Cox, the original Wonkette and now a writer for Time (and she of the obsession over anal sex) uses a Powerbook, as does gay faux-conservative pundit Andrew Sullivan. Writer/Director/Geek Kevin Smith is a Mac user, as is Joss Wheedon of Buffy/Firefly fame.
While they did initially move to an Mac OS 9 version in early 1999, they later moved to OS X according to Apple and the US Army:
"In June 1999, a Wisconsin teenager breached the security of the Windows NT system that hosted the site, replacing the home page with a defiant message from a hacker group. The site was moved temporarily to a Mac OS (9.1 - Swordmaker) — based system while the Army and its website contractor, CherryRoad Technologies, evaluated a number of platforms to ensure that such an incident could never happen again. After analyzing the security of a variety of platforms and reviewing security advice from the World Wide Web Consortium, CherryRoad recommended that the Army remain on the Mac platform.Today, an Xserve server running Mac OS X Server and WebSTAR delivers the www.army.mil content to millions of visitors each month. (That number has doubled almost yearly.) Despite the fact that the Army website is the target of hundreds of attacks every day, not one has succeeded since the switch to Mac systems in 1999. And uptime for the site is running at 99.995 percent."- June 2005

"The architectural firm that designed Bill Gates' $50 million residence, Bohlin Cywinski Jackson in Seattle, is a Mac shop, and Bill bought his mom a new iMac, because he said it was too hard for her to understand computing and the Mac is so much easier for a novice to use. Gates says his mom doesn't bother him so much with computing questions now. The high-tech electronics inside Gates' mansion are Windows-based. The first evening at home, his drop-from-the-ceiling bigscreen TV would not shut off -- Gates had to throw a blanket over it to get to sleep. - (Barbara Walters 20/20 interview)So apparently we can add Bill Gates' mother to the list...
