It has been four years since Apple Inc introduced a completely new gadget and the pressure is on for the worlds largest tech company to wow at its special event in Cupertino, California, on Tuesday. Apple has fed the high expectations, with promises by executives that the companys best product pipeline in 25 years is being readied inside its secretive facilities. Those now ubiquitous gadgets were created under the innovative and famously meticulous eye of Apple co-founder Steve Jobs, who died in 2011. When Chief Executive Officer Tim Cook takes the stage on Tuesday, technology aficionados, investors and rivals will be watching closely to see whether Jobs handpicked successor inherited the magic touch or whether Apples winning streak is coming to an end.
