A huge portion of the job for non technical people is ensuring hardware and software compatibility, installing, configuring the OS. With Windows people outsource this job to their OEM in general because that is what non technical people do with any OS they buy it as a package with their hardware and use it.
Using Linux isn't particularly harder than using Windows.
