I'll chime in for my WISP.
I live within the city limits of a suburb outside of Chicago which combined with the one next door, has 300K people.
FOR TEN YEARS I've been living here (some people have been here fifteen) and we still have no DSL... none nada zip zilch.
Comcast knows this, so they charge out the ass for HSI.
My WISP has been there through thick and thin. In 10 years only 2 lightning strikes have hit their tower. We started out on 802.11b and just moved over to Motorola Canopy voodoo... free upgrade to me. Now I'm getting 10M/2M all the time. Online gaming, online music, downloads, and my VoIP all work in harmony.
I couldn't be happier, and for only $60/month (including my publically accessible IP address) I'm pleased.
-- Side note --
My friend was opening a business. He had it all lined up to get AT&T phone+DSL in the new strip mall they were moving in to. Opening day November 1. He needed Internet access to run CC transactions.
AT&T comes in on Oct 28 and says "Sorry, we have no DSL for you here." ... get this .... "Go to an AT&T store and get the USB AirCard" He did despite my best arguement against it, and that option failed miserably.
He calls Comcast: "Sorry, we have HSI at the outlot, but we'd have to run a line to the main mall. Can you find 3 customers there that will need it?.... and if you do, it'll be 2 months to pull the line." Fail.
I call my WISP finally on the afternoon of the 30th. "Yeah sure, we can be out there today... oh wait, it's 3PM.... how about first thing tomorrow morning?"
So yeah, no fuss, no muss. Internet was installed on the 31st... up... running... and I got a couple months credit on my bill.
Score one for the little guy doing what the big ones don't want to, or can't.
The race of the Last Wire Mile is a difficult one, and when you can go through the air at the speed of light, WISPs will always win.
