But if I did download the video to my device ... I would still be able to play it. Same as if I bought a CD version. (the electronic version costs the same as a CD, btw)
So what Amazon is saying is: Because WE can no longer sell the movie, we aren't going to let YOU watch it ... even though we make it impossible for you to download it to any device with enough storage for your movie collection.
Or maybe they're saying: To store the collection of movies you buy from us, you have to purchase enough micro-cards to store them all. (and hope you don't lose any of them)
But as I said ... Lesson Learned.
Now I buy all my videos elsewhere, where I can download/store them on my PC.
