It would take a decade for a version of that DynaTAC phone to hit the market, for a hefty $3,900.
Truth be told. Henry T. Sampson developed the technology (gamma-electric-cell) two years prior to make the cell phone even possible.
Important reminder! “Too many engineers are wrapped up in what they call technology and the gadgets, the hardware, and they forget that the whole purpose of technology is to make peoples’ lives better”
