Although I agree with almost everything you said, it is not true that digital signals are either perfect of gone. The range of signal strength where they are marginal is much narrower than analog, but it exists. In that range you will see pixelation, temporary freezing, and even the audio going out of sync with the image. Rather than a weak, snowy image it acts like a poor connection.
OTOH where an analog signal is weak and snowy and not worth watching the digital will be sharp and solid.
I see almost no difference in my ability to pick up UHF stations at the longer distances than I do VHF. Many of our stations around here are operating both VHF and UHF and will continue to do so after the switch.
For those with outdoor antennas that get their present stations those same antennas should work well with digital IF the digital station is not at a different location. Years ago I put up a large Winegard UHF dish with remote preamp, on the side of a tower so I could watch the sci-fi programs on channel 50 out of Detroit. Just days after I put it up Channel 49 (a religious station) went on the air. They are about 1/3 the distance of channel 50 and in a direct line with channel 50. 50 went from a good picture to unwatchable.
Since going digital I've found I can watch many stations that were out of reach when I tried analog. So the number of stations I can watch as easily as the locals is about 3 to 4 times the number I had on analog. Yes there will be some that lose out, but I'd think they'd be few while many should be able to receive more stations. Of course there will still be the irate, uninformed (why didn't they tell us) group.
I find it amazing that so many have been informed, although I doubt half of them understand what they've been told. The old rule of thumb is at least 10% are always missed so the industry and government have done a remarkable job at informing the public with months left to go. At any rate, TV viewers are like computer users. Most are completely clueless. Of course for TV there is no real reason for them to be knowledgeable although they should know where to point the antenna.
the switchover and what's required is very simple, but everyone seems to be trying to make it far more complicated than necessary. I have to admit the cable companies are offering information that at times is a bit misleading.
I have quite a number of OTA stations I can watch in HD or digital SD, but seldom watch more than the local news. There is little the networks have to offer I find interesting although my wife never misses "Desperate Housewives". <
