I remember there was a time that is was predicted that with the advent of personal computers, that we would become a paperless society. In fact, we use many times the amount of paper now than we did back then. One person, when asked about this, said that in the '60s and '70s, paper was a storage medium. Now it is used as interface. We print it, use it, and throw it away for an updated version. The main reason for printed output was the volume of information you could put on paper vs what you could see on a 80x24 character CRT. Now we have word processors, browsers and large high resolution screens which can present a whole printed page at a time. The drawback then was portability; only desktop machines had a screen big enough to easily read those PDF documents. The new generation of notebook computers, IPads, etc will alleviate that problem, but now many desktop machines are sporting dual displays.
Besides, nothing is more relaxing, at least to me, than getting away from that electronic gadget, unplugging and sitting on the back deck reading a book while having a dog in my lap. But I'm sort of old-fashioned that way.
