"Yeah, right... I bet the board members at my company would really go for "Hey, let's install UNIX!". They would take one look at it and laugh their heads off. They would probably say, "Hey, while we're at it, let's bring back the IBM green-screen Mainframe's!". I agree, UNIX machines are necessary to run the Internet - the tasks they perform are simple, and that requires a simple OS. You don't use a space shuttle to fly from NY to TX, you use a passenger plane. The shuttle is far too complicated and wouldn't suite the job. UNIX and Linux are good for simplicity, like forwarding packets and handling DNS requests. The real work comes in managing global companies and government operations. "

You obviously have never worked anywhere with mission-critical applications. The hospital I work for has all the apps that can't afford to have even a slight hiccup running on some sort of UNIX. Those apps incluse patient registration/records, imaging machines like CT scans, and others.
