I am currently subscribed to Amazon Prime Video in Australia and if all goes well, in about 18 months, I'll be living in Thailand and would like to continue using the Amazon Service (especially since they've just got a deal signed to cover ICC Cricket Matthew matches for 4 years.
An Android Box would only be needed if one doesn't have a Smart TV, right?
What do you mean by "adons"? Are you referring to whatever streaming services that you want?
