IT MIGHT HAVE arrived in 2010, but it seems iPad had been lurking in the mind of Steve Jobs since 1983. In a speech at the Center for Design Innovation that year, Apple’s co-founder talked of putting “an incredibly great computer in a book that you can carry around with you and learn how to use in 20 minutes.” He added that it would also have a “radio link” for communication with the wider world. Reports suggest the iPhone began life as a larger device, but Apple pivoted to mobile phones. However, an Apple tablet did appear a few years later.
