The First Cellphone Went on Sale 30 Years Ago for $4,000

Somewhere in either Chicago, Baltimore or Washington, someone plunked down $3,995 to buy the Motorola DynaTAC 8000X, the first handheld cellphone, on March 13, 1984 -- 30 years ago today. We don't know who that first cellphone buyer was. At the time, the occasion didn't register as historically auspicious.
