Well we don't really have a choice. The industry uses windows and windows compatible programs. The data logging software we use requires windows. They build it for windows because it's available to everyone. Everyone uses microsoft office files too. I'm sure you could use something other than windows for the non data logging computers, and use another program to open word, excel, and access files, or simulate windows and office, but honestly I don't think it is worth the trouble. We have 9 computers in the office hooked up, and probably 12 portable laptops. The system is already in place too.
I know a lot about computers and dealing with them, but that's because I have used them my whole life. My knowledge comes not from a classroom, but 20 years of experience working with computers. Our systems do everything we need them too, including get viruses on occasion.
