How many Android tablets have out-of-the-box access to music stores, video stores, or ebookstores? iPxxx and FIRE do.
It wasn't until recently that Google got serious enough about content sales to restructure their Android store around content and most Android tablets not only don't come with Google store access, they need hacking to install the app.

People who buy Android tablets are more interested in hardware features or very low prices. Certainly the FIRE is no great example of fancy hardware features. But if you look at FIRE marketing, what do you see? Prime videos, Prime ebooks, Kindle books, Amazon MP3s. Look at the iPad and you see iTunes all over.

Both platforms are primarily storefronts looking to sell content and consumers buy them to do exactly that.
