Alomex,
Take Federal Government's DoD alone, based on articles, Sun's Solaris has been in the major servers, networks, worth billions of dollars, HP-UX was the second position. Other agencies, like NASA, NOAA, DOT etc., there are billions of worth of Sun Solaris, HP-UX. Small projects they would probably use NT. NT probably is a good OS in small to mid-size software, but when dealing with hugh data, Unix is still number 1.
I posted early before based on their percentages, and believe my data is correct. I wish Microsoft has more percentage, but the constraint on NT is its platform - Intel chips and its software. C, C++, Ada are used on Unix platforms rather than NT, and most of these languages are used to develop scientific/engineering application software. I don't think NT could break 10% of total workstations sold in enterprise.
Like I said before, Army ordered 200m+ of Sun Solaris from open bids a couple of years ago. Similar orders have been requested by other agencies. Unfortunately, I haven't seen a big order of NT servers from Federal Government.
You have to realize that 100% of college graduates majoring in science, engineering, and computer are all fluent in Unix systems. Nobody real care much about NT in the application development world. How can NT get more popular than Unix, that beats me.
