Break out your party hats and eat some cake because today the cell phone just became "over the hill." That's right, the cell phone just hit the big "Four-O" today. Time to setup your fake rubber poop and whoopy cushions because it's a cause for celebration. Just think about this... back in April 3, 1973, Marty Cooper, the inventor of cellphones placed the first cellphone call to his rival over at Bell Labs, Joel Engel. Eventually that device would be made into a commercial product, the Motorola DynaTAC 8000x. It was a 2.5-pound phone and went on sale for $4,000 in 1983.
Now you can find cheap throw-away pre-paid minute cell phones in the grocery story checkout aisle for less than $50 bucks, and our fancy smartphones are more powerful than the old school Cray-1S supercomputer and cost $300-600. Perhaps in another forty years we will simply have telepathic bio-silicon implants...
