You've completely missed extensions.gnome.org and gnome-tweak-tool, and as a result your review is not an accurate reflection of gnome-shell. Gnome-tweak-tool gives things like "Have file manager handle the desktop" and "Trash icon visible on desktop", plus shell, window, and gtk theme selection, font configuration, and gnome-shell extension management. Extensions.gnome.org provides, well, gnome-shell extensions. Things like "Static Workspaces", which gives you a fixed number of workspaces. Or "Alternative Status Menu", which puts power, reboot, suspend, and hibernate on your status menu. Or "Applications Menu", which provides a Gnome2-like list of windows on the current workspace.
Now, I admit that neither of these configuration options are immediately visible to a new user. Despite that, your review is bad, and you should feel bad.
