Taken from a recent article from the Telegraph in the UK , following Sir Clive's recent marriage in Vegas to his second wife, who herself has an intetesting background!
You will see he doesnt have a mobile phone and carries a slide rule with him.
" And the young, Surrey-born Sir Clive put his mind to an awful lot of different things. At 14, he designed a one-man submarine; by the age of 17, he was editing Practical Wireless magazine and selling earpieces to shops. Was he a nerd? “I’m not sure the word existed then, but I suppose I was: I got bullied a lot at school.” In 1961, after designing a pocket transistor radio, he set up Sinclair Radionics. The slimline pocket calculator followed in 1972, then the Spectrum computers. By the time he sold those off to Amstrad in 1986, Sir Clive was a millionaire.
Though not obsessed by technology (he doesn’t use a mobile phone, BlackBerry, computer or a car and has, since 1972, carried a slide rule in his pocket which he ironically deems “a lot handier than a calculator”), Sir Clive brightens at the mention of his current projects. In the corner of the room a stack of his new folding A-bikes are leaning against the sofa (“They’re half the weight of any other folding pedal bike in the world,” he says). And in his laboratory in east London, the Summer C5 (“the same concept as the old C5 with a completely new, improved design”) is being constructed. His great dream is to invent a “vertical take-off personal flying machine” to enable people to travel by air from one part of a city to another – and he claims to know how this can be done (“It will be entirely by GPS so you would just dial in where you want to go and take off”)."
