Ubuntu Welcome screen on first boot, once inside Gnome

Of course, Ubuntu (or Linux for that matter) is not Windows, and we don't want it to be. As a result, we do need to welcome new users in a friendly way, and I think the best way is a welcome wizard. Ubuntu, no matter how hard we try, will always be difficult to new users, because it's different. With a welcome wizard on first boot, or first use of a new user account, we could briefly go over the menu bar (Applications, Places, System), Apt-Get, Firefox, Thunderbird, etc. Really, the only programming that is essential is the first screen, then if the user wants to view the tutorial, they click continue, if they want to be reminded, click remind me later, and if they don't want help, just close and leave the link in a menu (system -> help). Then it could lead to an OpenOffice Presentation. Simple, but makes a big difference, giving Ubuntu an easier feel, and a more professional feel.
