Yes... and I LOVE it. We're saving upwards of $50/month over Comcast... the boxes run so much smoother, faster, and the DVR is MUCH quieter. Also, I really like the interactive guide. It, as well as the channel #s, will take getting used to, but overall, it was an excellent idea to switch.
The install took about 2.5 hours, not bad. We had 3 boxes installed, 1 of which is a DVR. With Comcast, we had 1 DVR and 1 normal STB.. however with FiOS, all TVs must have a box. But, we're saving a lot of money, so that really doesn't matter.
Any other FiOS customers here have good (or bad) stories to share?
