I have had FIOS for several months now and I have more likes than dislikes. The picture seems clearer, there are more HD channels than Comcast and the technical problems have been non-existent (I had tech problems with Comcast on a weekly basis, they never could figure out why or what to do to fix it and that never seemed to bother them.) The only negative aspect are the rental fees once your initial discount period ends. Their HD boxes and regular digital boxes are more expensive than Comcast, as is their DVR. When you factor in those prices for me the monthly bill is no different than my Comcast bill was. However, I do feel I get more for my buck and the service in my opinion is better. I don't miss Comcast at all.
