Except their routers are awful. Too high a failure rate, and for some reason they route their guide data and VOD through it, so when I took it out of my setup, the one FIOS box I have no longer gets any guide data (my main TV uses cablecards, which don't get VOD anyway).

I've dealt with a couple ISPs who give you routers/modems with little to no options in their admin screens. It's really annoying. I've even seen one that a) only used WEP, and b) did not allow you to change the router's login info. Incredible.
