iPod 

Someone put a "citation needed" after my addition of "iPod".

Why? None of the other examples has citations. Why is this needed for the iPod?

Google has  (lots of examples) where "ipod" is used as a generic term for a MP3-player, but is a 'citation' from Google sufficient?

Or how about "download to you iPod" where downloading is really just a MP3, that can be used on any MP3-player. Is an example like that sufficient?
