During the days of dial-up internet you could have said the exact same thing about broadband. Jump forward a few years and we get YouTube, Netflix, and other services never possible before high speed internet existed.
So what I'm getting at is, we didn't knew then what was possible with a fast connection. I'd imagine we'll see a dramatic change in the way data flows.
Say what you want about the Comcast caps, it seems to be the only solution for those of us stuck in a city like Houston where Verizon is not going to be able to reach us with Fios and Uverse is stuck at 24MB down. With Comcast at least I have options for 30, 50 and 100MB although it would be nice to see 100MB drop from the ridiculous $199 a month for people who are not in some sort of triple play. I like to buy my bandwidth and TV separately and until Comcast can do Anyplace DVR I have to stick with Uverse to achieve the view anywhere in the house solution the family loves.
