A coworker told me he was getting symmetric gigabit from AT&T for $70/month so I decided to check them out. I switched from Comcast and everything has been awesome except for the supplied wireless router. My iDevices will not work reliably on it so I added my own.
My bill dropped almost in half and I got away from Comcast's metered, expensive, less reliable crap.
I am in Atlanta so the 'threat' of Google Fiber may explain the great deal I got. Not affiliated with AT&T at all and am honestly surprised at how good the service has been. YMMV
