Not me. They got us a FIOS deal when we got our house. I used them for 2 years. Super fiber speed, except they would throttle youtube. So here I was paying to this supposedly superior quality and speed and getting throttled by them. So I dropped them and switched to a plain old cable provider (just for internet, we don't really watch tv anymore). Cut my costs more than half. On paper the speed is lower, however, the latency and lack of throttling for things like Youtube and other media is better.
Now since Verizon installed their equipment on our premises, they keep coming back every few months, in person -- as in they have someone drive out to our door, begging us to come back. They even offered to match the price we pay for cable currently (but it is always some stupid 2 year contract thing, that I know will go throught the roof when the time is passed).
