It's not supposed to replace the panel or am I

Well, to a certain extent, it can
replace the panel. There is now an "extras" archive that provides AWN applets that duplicate (in a visually slick way) most of the functionality that we usually use the gnome panel for: user space switching, window selection, battery monitoring applet, calendar applet, user notification area, and so on. There are only a couple of things not yet available in applet form, and one of them is something like the networkmanager applet and the powersaved applet.
