I got my first mobile phone in about 2002: it was the classic Nokia 3310. It was, at the time, at the cutting edge of technology. Since then, I have owned a Blackberry, a Motorola Razr (that was stolen from me in a restaurant in Turin, still grates me) iPhone, brief flirtation with a Windows phone and now I am back with an iPhone. All of these phones were acquired because they offered me something. The Blackberry was good for email, the Razr was small and didn’t look funny in my pocket, the iPhone had a good camera. I have no idea why I bought a windows phone. Recently I was clearing out some drawers in my office and I found numerous chargers for all these devices. Over the years my lack of commitment to one device has meant that I have kept all of them, thinking I may have a use for them. But in the 20 years they have been in there, I have never needed any of them.
