Booting the cd is necessary to ensure that everything is working correctly before you install it to the hdd. Ever installed windows before? It takes 8 or 10 reboots to get the job done. I don't think that booting into an OS and having the ability to surf and get help while you install is a bad thing at all. Surely a noob would be more annoyed if he/she installed and then found out after the install that some things weren't set up before they did the install. Perhaps having the option there at boot would be seen as a recommendation to just install it and not to worry about whether or not it works correctly.
