The Most Prolific Consumer Device on the Planet

BBC -- "More than a billion mobile phone connections have been added to the global tally in just 18 months, and there are now more than five billion connections worldwide - which is three times as many phones as personal computers.

In the UK in 1987, when the first mobile companies launched, an industry insider predicted a maximum of 10,000 phones.  Now 30 million phones are sold every year in the UK."
