My wife found this yesterday - I missed it when it happened in December. This is huge - at least for us. Living in the US, Amazon Prime is now one of life's irreplaceable building blocks - kind of like phones that find addresses and play music. Most of our TV watching is now based on the Prime offerings, Netflix relegated to second place.
Included in the Prime subscription are Acorn, Starz, and several others that would cost money separately. The non-TV Prime advantages, such as free Amazon shipping, are sadly not of much value in Argentina, but I'd consider subscribing for the TV offerings alone.
We'll be in BsAs for the next six weeks, so we'll see how much of the content is available. Is anyone currently using the service and can give some insights into what, if any, limitations are imposed?
