Yeah, everybody would be more productive with a Unix server on the desk.
For the most part, if they took the opportunity to learn the tools it comes with.
I often have to deal with massive numbers of files, text, and data. I couldn't imagine trying to do what I do in windows. Something that is a 5-minute affair with unix, would be an all day task, if not more in windows, because it just doesn't come with the kind of basic tools for manipulating data that are standard fare in any Unix.
