The evolution of the mobile phone

PC World traces the evolution of the mobile phone in a pictorial essay

Since the introduction of the first "mobile" phone — the 88-pound SRA/Ericsson MTA (Mobile Telephone System A) — the now-ubiquitous cell phone has morphed from a heavy-duty, heavyweight, vehicle-mounted appliance into a handheld terminal that fits in your back pocket.

What once cost several thousand dollars per unit, with a weight measured in pounds, and offered battery life of less than one hour can now cost as little as  $99, weigh 4 ounces and pack five to 10 hours of battery life — not to mention a full-fledged computer, video camera, audio/video playback and high-speed Internet access.

PC World traces the evolution of the cell phone in the past five decades in a pictorial essay here.
