"Three years ago today, on January 27, 2010, Steve Jobs stood on a stage in San Francisco.
"First he talked about how Apple invented the modern laptop in 1991 and revolutionized the smartphone with the iPhone in 2007.
"Then he asked: "Is there room for a third category of device in the middle? Something that's between a laptop and a smartphone?"
"After trashing an existing category of devices – the netbook – Jobs's tone of voice changed. It grew hushed and fervent.
"And then he said: "We think we've got something that is. We'd like to show it to you today for the first time. And we call it…the iPad."
"The world hasn't been the same since."
