I REMEMBER that chilly January morning in 2007 when Apple's chief executive officer, Mr Steve Jobs, received a wild reception unveiling the iPhone at the Macworld expo held at the Moscone Centre in San Francisco.

No buttons graced the iPhone save one: home. Instead of a keyboard, users used a finger to swipe, tap and flick the 9cm touchscreen, to activate a function like SMS or scroll through contact lists.

Users could turn the phone horizontally to read a Web page in 'landscape' mode. The device could store and play thousands of songs. The iPhone was a phone, I discovered, as well as an iPod and a mini-Internet computer all at once.
