Ok - I just had my service installed yesterday and everything seems to be running great! I consistently get 28.6Mbps download and 9.6Mbps upload with a 3ms ping time - faster than expected! Also the TV is up and running although the guide seems a little slower than TW. All in all I'm very happy with the service so far.
I also just switched from TWC. FTTN and 3200' of copper to the house. Line tested at 35Mbps. Install was painless and all works as promised. UI on the DVR is a bit clumsy and the available free on-demand programming is lacking, but for $100/month savings, I can deal with it.
