In Houston we originally had RoadRunner broadband via TimeWarner, which changed recently to Comcast. Service was getting bad with TW, and hasn't improved with Comcast.
Waaaaayyyy too much latency, lost connections, etc. When I'm home, I typically have to reboot the router every other day. We've been told that our area is "saturated" with subscribers.
I'll fire up IE, type in Google, hit the enter button, and sometimes wait 3-4 seconds for the page to pop up. Downloads are lightning fast, however, once they get started.
We have their "premium" 7.5 MB package and pretty basic HD digital cable service, and no premium channels, with two TIVO HDTV boxes for around $130 per month. If there was a reasonable alternative, I'd switch in a heartbeat.
In the UK, where everything typically costs double what it does in the US, my mates have Virgin cable, with a premium channel package, 9 movie channels, 20 MB Internet service, and VoIP for less than what I'm paying.
We're being royally screwed in the US by these ISP's, guys.
