The Pew folks have rolled out another hilarious study that suggests most dial up users don't want broadband.
I have observed this phenomenon for fifteen years now--much longer than the Pew folks. It is very simple, really. People that have never had a broadband connection are, in fact, likely to believe it is something that they don't want or need.
But here is the problem. The Pew folks have never asked broadband users if they would go back to dial up. And you need to ask that question in order to be able to understand the survey results of the dial up question in the appropriate context. We all know the answer we would get from broadband users: no one wants to go back to dial up. In fact, I've been asking that question to rooms full of people for many years, and I have never had a single broadband user stand up and say, "Oh yea, broadband is waaaay too fast for me. I'm switching back to dial up next week."
You need to query both groups with the complementary version of the same question if you want to be able to draw any useful conclusions.
