On Linux and Mac OS X

I've mentioned that I use Linux and OS X at home and Windows XP at work. I am amazed at the mediocrity that most people will settle for, and, in some cases, even prefer. Being a start-up, we don't really have the budget for an IT department, per-se. Because of my background, I am the default computer guru, along with another of my co-workers. I deal with Windows problems constantly. I can see peoples' argument that Mac's are too expensive, but, for goodness sakes, Linux is free. The latest distributions of Linux are easy to set up and use. I sometimes think that if a miracle cure for AIDS were discovered and it were offered to 100 people, 90 of them would decline because they were accustomed to their current medications. Are people really so stupid and/or helpless?
