Mobile phone turns 40

The mobile phone turned 40 on Wednesday, with no fanfare to mark the occasion

There was a program on DSTV 2 weeks ago that covered this and interviewed Martin Cooper. He spoke about the engineering challenges they faced.

Can you imagine carrying a phone literally the size of a brick, weighing 1kg and battery life of 20 minutes?

And look at Motorola now. RIP.
