Obscene? lol...we don't have cable and stream everything via multiple devices, it's not tough to do, and we did it to cut our entertainment costs in HALF. This entire situation comes down to good old fashioned greed. ISP's want users to pay more for less.
That being said, make pay-per-GB affordable and I won't care. But that's not what will happen. ISP's like Comcast, which have a 250GB cap for now, would love to make the internet so UNaffordable for high bandwidth applications like streaming video from a competitor that you will have no choice but to: 1) Switch to their cable service 2) Pirate from your local Library and DVD-in-the-mail's
And all the while, the U.S. will keep falling behind in consumer Internet speeds and pricing. It's a beautiful thing
