Apple has already transformed two industries: music and computing. Now, as the company reportedly attempts the redefinition of the watch – one of man's oldest pieces of technology – the next phase of the techno revolution is hoving into clear view: welcome to the age of "wearable tech", with a gadget available to cater to your every need. Inevitably nicknamed the iWatch, the Apple device, on which the company is characteristically not commenting, has the tech world in a frenzy of sci-fi speculation. But the internet revolution seems to have largely bypassed the watch, until now. Apple reportedly has 100 employees looking at the device that will take advantage of recent developments in hi-tech curved glass, cheaper sensors and better voice recognition software. The company will want to make a splash. Especially as archrival Google has its own "smart watch" in development and is already testing Google Glass, web-connected specs. Google co-founder Sergey Brin was recently snapped on the New York subway wearing the glasses and looking like a tourist in town for the marathon. Amazon, Microsoft and Facebook too are watching developments and have their own plans.
