Most linux distros are easier to install than Windows.
I do understand what you are saying, though. Linux was never meant for someone who knows *nothing* about computers, though it can be used by such.
DOS (and Windows later) was originally intended for end users, and not techies. That was IBM's market. Linux was targeted at techies, and was Linus' school project in a tech class at University. Big differences in origin, thus big differences in design and use concepts.
That being said, though, Linux today is just as easy (if not easier) to use as Windows. It *is* different, though. The same tasks will use different steps than Windows uses.
