LMFAO. You must be joking.
This is the kind of nonsense you hear from someone who really can't/doesn't/won't understand the whole of the Apple ecosystem. Amazon has nothing to compare to. They have a website, where you can buy em pee threez. Big deal.
Amazon sells books, movies, music and apps. So for many people - it's a full ecosystem. What (not quanity) does Apple sell that Amazon doesn't in terms of content?
And if you already have a smartphone then why bother?
Screen size?
