I’m with the latter group, mostly because, whenever I think about new technology and its potential to go mainstream, I remember the Rule of the VCR. Every household had one. They were easy to set up and use, and using them fully offered people the great benefit of watching TV on their own, not the network’s, schedule. Yet in more than 9 out of 10 homes, the VCR might as well not have had a “record” button; it was put to its simplest use, playing tapes.

The Rule of the VCR states that in non-vital matters, people follow the path of least resistance, even when only a little extra work will bring great benefit.
