The first time the iTunes application is launched a Welcome screen appears by default.
There are four primary options, Learn more; Take a quick tour; No Thanks; and, Agree.
When the Learn more link is clicked, A browser window opens a Sharing Information About Your Library with Apple webpage, which is consumer-friendly page. The content is brief and to the point. It outlines the benefits of sharing your information with Apple. For users who like to read legalese, there is a link to their privacy policy.
From the Welcome screen, when the Take a quick tour link is clicked, iTunes Quick Tour appears in a new window
Once the last slide is reached the Next > link disappears.
I hoped to see some sort of Get Started or even Close button appear in place. Instead user must close the window using standard window controls in top left corner.
The iTunes Quick Tour can be accessed via the iTunes Help menu, however this information is never expressed to the user.
