How to view a list of register Apple products

This is very easy and all the other support articals are wrong! Apple's own article on how do this states :

If you used your Apple ID to register or purchase your iPod, you may find the serial number listed in My Support Profile (available in the United States and Canada). Log in with your Apple ID and find your iPod in the "My Products" box on the main page

that link is: https://supportprofile.apple.com/

You're welcome.
