Can we just not call it nix? I think that is what is confusing. Maybe its just the most popular desktop linux format (at least currently) or something else. It is kind of weird to talk about a standard nix interface that isn't a terminal (at least it seems that way to me). Every linux box I use always has different desktop/X-environment from the next. There may not be thousands of X11 desktops, but there are quite a few (cde, enlightenment, gnome, kde, xfce, just off the top of my hdead) that all have their differences. I would agree more with the other guy, but acknowledge its pedantic details.
