When you pop in a DVD burned from an Xubuntu installation ISO you get two buttons, which allow you to choose to try Xubuntu or to install it. If you click the second button, to install Xubuntu, the installation starts off after asking a couple of questions. One of the first panels which displays while you're waiting for the installation to run its course suggests that you try using the system you're running to get a feel for the interface, which it says will look very much like the installed system. Why would it say that if you didn't choose the first button (to run the system from the DVD)? I think it would give new users a more confident feeling about the system they're installing if their first impression didn't make it look like the folks who created the installation program were asleep.
