It was easy for me to drop comcast
Not that I was not a happy customer, I would be a customer again if they were in my new area.
"I need to cancel my service because I am moving and you don't have service in my new area"
"Oh, are you sure you want to cancel what is your new address?"
(tell them my new address)
"Oh we don't serve that area, sorry to see you go!"
Took all of about 2 minutes.
My new cable provider to me is about the same as Comcast service(overall probably less service but those services that they lack are ones I don't use), performance and cost wise, though it is a small fry by comparison only serving the city I am in (apparently has ~42k people).
My bill is about $170/mo with most premium/HD channels and standard broadband (~16Mbps down / ~2Mbps up). It serves me well I just wish I had better upload speeds(I have a server at a colo with unlimited bandwidth and TBs of space about 15ms away). Even their top tier 100mbps service has only 5Mbps upload.
I'd be happy to pay Comcast $110/mo for their business class service with 50/10. There are no plans with 10Mbps on my cable provider for any price(on the website anyway).
AT&T Uverse keeps pestering me at least twice a month every month to sign up, but my Tivos don't work with them, so that is a big drawback, they don't offer anything special over my local cable company anyway (internet speeds may actually be worse with IPTV I am not certain).
I was a Comcast (and before that AT&T Broadband) customer for about 10 years or so, never really had a problem. I did stream netflix for about 6 months or so before I lost interest in their lack of content and haven't been a customer since their first price hike (mainly because I realized I wasn't using the service). Never used any of the "on demand" services from comcast, nor voice, nothing but tv(via tivo) and internet.
