Only thing I'll miss about analog is that even a 50 year old TV would still work (theoretically) or those little mini portable TV's, but ah well. And people need to remember that the already low powered stations will still be able to be up. Granted that may not amount to much programming choices but eh, its something. And honestly I am sure that after the switchover date you'll see at least one or two media outlets using some of the UHF bands to broadcast stuff, even if its iffy crap, its still something. I suppose that in a time of emergency or something, they could also use one of the old VHF bands for emergency broadcasting, which would fit into their plans to use the old bands for emergencies, so that every one, no matter if they have a new or old tv will be able to get the information or if something happens to the digital transmissions.
I do merch work at Best Buy and I think they would like to see this switchover happen sooner than later anyway. Pallets upon pallets of convertor boxes all over the place.
