Yes, a shame this is getting missed. I think a lot of folks probably have no clue that you can receive HD channels in your home with no cable TV service whatsoever. You just have to buy your TV, HD antenna, and pay your electric bill.
If you also buy a photovoltaic system for your roof and some batteries, you can go totally off the grid, no additional payments to the electric company, and still watch your HDTV.
Absolutely true, especially in any of the "major markets".
I ditched cable after the digital conversion, and recently sprang for an updated TiVo w/Lifetime subscription.
The money I saved from cable pays for the TiVo after one year. TiVo also supports NetFlix, BlockBuster and AmazonVideo so I have lots of choice to get "non-broadcast" content (like PPV/OnDemand movies or Cable Only shows that don't show up on Hulu like Dr. Who).
Throw in a PS3 as a DVD/Blu-Ray (not to mention games) and you've got a pretty decent setup that has access to lots of content and sources (Amazon, BlockBuster, NetFlix, PS3 Video Store), has a DVR with decent recording capacity (on the TiVo), Dual Tuners for Over The Air time-shifting (CBS, NBC, FOX, ABC, WB, ION, PBS, +sub channels with local news and weather 24/7), with no monthly costs (other than the Internet connection I'm already going to pay for).
Yes, there are some things I miss about ditching cable (SciFi Channel, Discovery Channel, Food Network, BBC America). Some of that I can replace via other means, some of it I just do without. With two tuners recording things I might like, there is more than enough for me to watch already, and saving $100 a month is nice.
If I had a chance to "get some of that back" by subscribing to Hulu+ for $10 for an easy to use user interface, and not having to add an HTPC to the existing setup? I'm sold.
I was thinking of dropping a Mac Mini into the mix to handle Hulu and other "Over The Internet" TV, but this could nix that decision.
The main reasons people DON'T think about Over-The-Air broadcasting are:
1) For a long time, especially in big cities where there were a lot of stations, reception was spotty. Digital signals have done a lot to fix this (in my experience).
2) There is something on Cable that they can't picture living without (Sports, Kids Channel, etc.)
If you can get beyond #2 and explore if #1 is still true for you (first step for me was buying an antenna w/amplifier and seeing what signals I got), then it might be worth it for your time.
