Prototype Design Question

My specific question about the prototype would be “Why would a user use the “View Options” button instead of just going to “Preferences” in iTunes?” I mean, why not to put “Customize Homepage” or “View Options” settings into “Preferences” and doesn’t this button confuse most users leaving them with the feeling of duplicated settings? I think, unless instructed a user might not use that button, he simply might not know what the button does, even though it says “View Options”. It would be perfectly clear for users if the iTunes Store homepage has tips or quick tutorials along with “View Options” button. Otherwise, users may ignore the button and keep being unsatisfied with the Store homepage when they did not find customization options for the Store homepage.
