Today we take for granted being able to pull a cellphone out of the pocket and making a call to anyone else in the world, but there was a time when that seemed like science fiction. In fact our trusted cell phone is "only" 40 years old, although I doubt many youngsters would still be able to even pick up that "brick" they called cellphone back then.
The first phone call using a cell phone was made by Marty Cooper, working at Motorola, that decided to ring a friend working at the competing Bell Labs, asking him "I'm ringing you just to see if my call sounds good at your end."
If you think current smartphones are heavy and have lousy battery life, you'll like to know that back then, the Motorola DynaTAC 8000x (the first commercially available mobile phone) weighed 2.5 pounds and it lasted for about one hour of talk time. And let's not forget about price: at $3,995 it would be enough for you to buy nearly every single high-end smartphone today, and still enough to spare for next year's models.
