I too was very lucky to go on house calls as a boy as the helper to a great man. It was great to visit the different people. I often try to find any of them that may still be alive. Seems crazy to many but i think everybody i ever met is special to me.
i love these tv's and all related things because they help keep the memories of loved ones fresh, both gone and those who are still here. I love all this great technology and history for all the reasons mentioned by others. To see all those tubes light up on my ctc 15 was always a great thrill for me and mostly to see the exact beuatiful living color programs exactly as my loved ones and the rest of the world saw is one of my greatest pleasures.
now, if i can just get my mom to watch it with me...

... she is still afraid to enjoy the past completely.
