HT204074 How do I see what devices are associated with my iTunes account?

Question

http://support.apple.com/kb/HT4627 contains this advice:
Your Apple ID can have up to 10 devices and computers (combined) associated with it. Each computer must also be authorized using the same Apple ID. Once a device or computer is associated with your Apple ID, you cannot associate that device or computer with another Apple ID for 90 days. You can view which devices or computers are currently associated, remove unused devices or computers, and see how long before they can be associated with a different Apple ID from the Account Information page in iTunes on your computer:
Open iTunes.
Sign in to your Apple ID by choosing Store > Sign In from the iTunes menu.
Choose Store > View My Account from the iTunes menu.
From the Account Information screen, click Manage Devices.
Sadly, "Manage Devices" isn't actually there, so I can find no way of seeing which devices and PCs are associated with my Apple ID and how to delete or add to them.

Answer 1

Manage devices relates to the devices or computers you have set up to automatically download content from your iTunes account aka "iTunes in the Cloud". You can have up to 10 such devices. This is a separate list from the list of 5 computers that can be authorized to play your protected content. There is no similar feature to list this second group, but when you get to 5 computers you can choose to deauthorize all and start again. You cannot use that feature again for a year.
