This is a fun article on MSN.com that looks at the evolution of the indispensible cell phone.
The SRA/Ericsson MTA looks from 1956 like one of the wall-mounted phones on the Battlestar Galactica (the SRA weighed 88 pounds!).
The Nokia Mobira Talkman from the Orwellian year 1984 looks a lot like those old Army phones you saw on the battlefields in World War II movies. "Call in an air strike to these coordinates!"
Our own cell phone looks so 2002. Screw it, give me a communicator any day.
