Check out this article from the U.K. publication called ISP Review. They did a survey of 721 respondents that revealed "75% of readers would not buy a house, even a lovely one, if the best broadband ISP speed it could achieve was just 1Mbps. In addition, 51% would be willing to pay more for a house with "faster" broadband." Even more interesting is the comment section where folks complain about the U.K. goal of 2Mbps per home by 2012.
Makes you wonder what the kids at the FCC are doing right now on the U.S. national broadband plan. My advice: go big, go bold and start from a clean slate. Inspire us to build a great foundation for the future.
