I believe that eventually Amazon, like many others, will start accepting bitcoin as payment but I don't think it can happen this soon (about 5-6 months). I think most of them aren't yet sure about enough revenue could be generated this way and may be still worried about the fees. For example take a look at the past 24 hours, as price started having a small rise we had another spike, although people are still paying low fees but the mempool size grew as big as 100 vMB.

I agree. This will definitely not happen, not to Amazon and not to any other company. A lot of things went wrong with Facebook and the headache is not worth the effort not to mention that the product with be garbage and people won't use it as long as there is fiat and there is bitcoin.
