Still so much of a pain in the ass to actually pay for it, especially if you're out of the US. They're just throwing money away by not giving us this option.
God it's like when CBS or another US network puts a video up on youtube and then sets it so that you can only see it in a few countries. Why the hell would you do that, I want to give you money (indirectly at least, putting up with your ads). I guess it's some legal crap.
Edit: Just out of curiosity, I'm looking at that HBO Go thing for the Philippines (where I'm from), and they want me to contact my cable company or something. And then dealing with them isn't a walk in the park either. They need to realize... if I can't just press a button and give you my money, I really don't want to make the extra effort to do it.
