This is true, but ten years ago it was not so hard to envisage that there might be a demand for using the web to show moving images. TV already was widely accepted consumer technology. Now, this is all fine in hindsight, but apart from HD TV I struggle to think of more data intensive applications that would be of use to the general public. I may well be wrong, but I just don't see the revolutionary applications that need that sort of bandwidth yet. And lets face it, 99% of people that are hungry for 20 Meg speeds just want it so they can grab that DVD in half the time. I don't download much, and watch the occasional footie match on the web (though the quality of that could do with some improvement), so I will probably stay put at 4 Meg. I suspect a lot of others will do that as well. In fact, I wouldn't be surprised to see many ISPs move to a usage based business model in the future where everyone gets top speed, and you get charged per Gig you pull down, as too many customers would find the lower speeds serve them fine.
