Long time passed since starting this thread! Seems kind of quiet here...but I guess that's a good thing!
Just stumbled upon this thread and have to say short that as former Florida resident (Ft.Lauderdale area) I have to say I was with others in the bushes with slow local service provider. Comcast in SE Florida is a joke with DSL cable speeds except for first couple of minutes of use where they boost you to advertised amazing internet speed. Besides them there is nothing much else to choose from.
Even more I became happy resident of New England with light speed Fios cable services which I use for last couple of years. Hope they will wire south part of my home state soon for the benefit if many users longing for fast and reliable service down there.
