Bandwidth costs money, and I assume Comcast does not want to raise the price of their HSI offerings (especially considering all people do is bitch about it being too expensive already)

Not everyone who uses the internet is as web savvy as the people who post on this board. We have to realize that we are in the minority and that these ISPs such as Comcast, are trying to appeal to the masses (thats where the real money is). Bandwidth and Speed hungry niche markets will find their services with FiOS for the time being. I believe that once it becomes strategically and financially necessary to compete with FiOS' speed offerings on a national level Comcast will do so and all these discussions will be moot.
