Rural areas are ripped off the most. In areas where only one telephone provider or one cable provider holds the monopoly, they charge 50-70 dollars for next to no speed.
For instance, in my area, I cant get cable. Only DSL. The DSL prices are 55USD for 512kbps down 128kbps up, 65USD for 1024kbps down and 256k up, and I currently pay 76 for the business line DSL, just simply for the static IP. Infact, when I first upgraded, the local frontier office cancelled my account. When I called to ask why, they said that they dont support buisness line. And I'm farily certain that gentleman was fired after my next call to frontier, where they did support buisness line, but werent going to increase my speeds at all. So now I'm paying 11 dollars just for static ip. Fun.
Even better? Talked to a friend in a metropolitan area who also uses frontier. He is getting 15meg down, 3/meg up for 45 right now.
Frontier and every other ISP who rips off everyone every chance they get can all go to hell.
