I wouldn't DREAM of dropping cable without having a decent OTA HD setup in place first. Local news, special broadcasts, etc. You're over-simplifying the issue. OTA should definitely be part of this conversation.
Also, antennas being 80's technology? You are living in the twilight zone man... I would bet good money that 90% of this world does not have Satellite or Cable television.
I'm over simplifying the issue for you maybe but I'm afraid it is in fact that simple for me. Reason, I don't like local news and don't care much for the Grammys. So now you see how it's very simple for some but not you. We all have different viewing habits and needs.
As far as people with antennas, I'm really sorry to hear that but I don't mention the lure of pagers during a conversation about cell phones and you shouldn't either if you expect a reasonable response.
