72    % talk about the difference between a desktop environment and a window manager:
73    % a desktop environment (like GNOME, KDE, Xfce) is a collection of
74    % programs, libraries (including a graphical toolkit) and configuration.
75    % it usually aims for a coherent look and feel and comes with a number of
76    % tools (g*, like gedit, geeqie, …)
77    % One of the programs of a DE is a window manager.

87% compare this to a screenshot of i3:
88% notice the little amount of toolbars.
89% notice the lack of fancy window decorations
90% notice the absence of a desktop.
91% instead, you get to use the full screen.
