When I first had FIOS installed back in July, I was ecstatic over the increase in PQ, especially for SD channels. I was less than pleased with the PVR, since I was use to Dish's best of breed 622.
But, Verizon has updated the IMG (still needs work). Better yet, in the past two weeks I've noticed an increase in speed and overall stability with the operation of the Moto PVR.
Come on guys, Verizon isn't a fly-by-night operation. They will deliver the goods, and provide the competition this industry desperately needs.
As for customer service, YMMV. Dish/Cox/DirecTV/Comcast is no better nor worse.
It is what it is.
