Here is mine:
1. As a mother, I loved this, esp. when driving with the kids.
2. Chimed to turn the pages.
3. My kids loved the Disney ones. We had a case that would hold both parts. It stayed in the car.
What would it be today? We Techno4 people use it with our kids - on the computer or iPad. We even make our own.
I do not really have something OLD or VERY OLD like you guys but I remember helping my sister do her homework:
It was portable, heavy, used paper, and your finger gets red after using it for awhile. Poor sister, when she did a mistake, she needed to start over .
I found out that my grandma has a room fill with this machine but in previous model (when they were not portable)
