I had road runner cable internet, dish tv, and verizon phone for years.
I recently switched to Verizon for everything.
I ended up with the same monthly bill, but here's what I got over what I had before:
HD channels (dish would have charged me more for those)
20MB download/ 5MB upload (compared to cable with 7MB/512kb)
I could have saved some money going for 10MB/2MB, but there are times when I could really use the 5MB upload, so that's what clinced the deal for me switching to FIOS. The most cable would give me was 1.5MB upload, and I would have had to pay through the nose to get it.
Here is what I lost:
Great customer service. Verizon has had great difficulty getting my order right. Specifically, I didn't have the 20/5 service for a couple of months despite specifically switching to FIOS for this ability. Of course they weren't charging me for it either... but I really had to nag them repeatedly to get this service. Their 1-800 menu blows... designed to keep you going in circles before you actually get to anyone who can help you.
Also, my landline phone now has background interference... like a tv or radio station always talking on it with some static noise thrown in for good measure. Haven't had the time to get them to come out and fix it.
Finally, their router blows. It has some nice features at a glance, but the NAT doesn't seem to work nearly as well as my Linksys WRT54G. I have found information online to allow me to turn their router into a bridge so that my WRT54G gets the WAN assignment, but I haven't had time to mess with that yet. Hopefully, that works and restores me back to the full port forwarding abilities I had before to support hosting games, etc. as even setting a PC to DMZ doesn't quite work with all my games MP interfaces.
What sealed the deal on my decision to switch is when road runner suddenly failed for no reason. tech came out a few days later, had it fixed by replacing all the cable terminals and eliminating a filter that blocked tv stations... then a week later internet went out again. So out of 14 days, I had maybe 4 days of internet. I don't know what their problem was and don't care. FIOS hasn't dropped out yet. Road runner was also in and out all the time when I first moved in to this neighborhood. Took a coulple of years before it got fairly reliable.
Verizon HD channels are pretty darn good. Look great on my 46" 1080p lcd tv.
