>I think I need something better than that. You are talking about 2 physical items, I don't think anyone would argue just because you buy 1 product off the shelf doesn't mean you are entitled to the rest of the shelf...

Let's say you are an iPhone user and you have bought a bunch of media from Apple. Maybe you really hate the next iPhone announcement and want to move to Android. Would you expect Google to give you a free copy of all the media you originally bought from Apple?

Also you have to get away from the idea that the price of the content is dictated by the costs to produce that content. That production costs is only the minimum price that would allow production to continue. Prices for digital goods are often just dictated by what the seller thinks demand is (since supply is practically infinite assuming there are no contractual restrictions).
