There will always be the select few that will wait till the last possible minute to do anything about it! Kind of like the day before Christmas and every store is packed to the ceiling with "last minute shoppers". Like you just found out Christmas was tommorrow idiot!!!!!
I worked in a phone office for a couple years and I was amazed at the number of people who wouldn't pay their bill each month until their service was shut off. And it was the same people every month, we'd do the disconnect for non-pay and sure enough the same regulars would come into the office to pay their bill and get their service restored. Mind you they got charged a reconnect fee each time too, so they were spending more money every month just because they couldn't or wouldn't pay the bill on time. And sure there's issues with people not having enough money to pay their bills but with these people obviously they had the money because they'd come in to pay the bill everytime on the same day it got turned off. So in my experience the only way to motivate some people to do something is turn off their service and they'll finally get off their couches and do something about it. So the best thing that could happen for those who are still "unready" for DTV is to turn off analog broadcasts.
