With all of the PSAs and crawls being done for months now, it's virtually impossible to watch TV and be unaware of the transition. At this point, I'd say that "unaware" translates to "don't care" ('cause the person doesn't even watch TV, especially OTA). But, sure... let's just go ahead and delay it because 3 out of every million might be inconvenienced if they ever do try tuning in with their old TV (/sarcasm).
