In the endless religious war against who’s better between the MS proprietary operating system and the open source Linux world raises up the war of prices. And so people move from sentences like “Windows is bad for abc reason” and “Linux sucks because xyz doesn’t work as I’m used to” to stuff like “Windows licences costs too much” or “Linux is free and so you’ll pay nothing of nothing”… in this crowd of phrases I’ve found an article, a simple and clear one: Enterprise Linux vs. Server 2003: Smackdown!. It’s old but not too much.
