Linux is more complicated/sophisticated than DOS/Win. It will never be
accepted (in its current form) as a mainstream OS not because its Linux, but
because its Unix, i.e. Unix has never been known as a mainstream,
user-friendly OS.
On the other hand, keep in mind that the feature we are talking about (file
permissions) is related to Unix's multi-user personality and is something
which DOS/Win doesn't even have.
There are things that will improve the situation too. I'm eagerly awaiting
a stable GNOME implementation, plus a good GNOME-aware window manager.
