Quote "When I was young, the concept of being a dreamer was a very negative one. If you were a dreamer, you were useless. You didn't contribute anything to society. But Star Trek made dreaming legitimate, and I think that was a huge, huge contribution. ~ Martin Cooper "People want to talk to other people - not a house, or an office, or a car. Given a choice, people will demand the freedom to communicate wherever they are, unfettered by the infamous copper wire. It is that freedom we sought to vividly demonstrate in 1973." ~ Martin Cooper Fun Fact-Motorola introduced the 16-ounce "DynaTAC" phone into commercial service in 1983, with each phone costing the consumer $3,500.
