From Executive Diary to Smart Phone
Back in late 1970s and 1980s, I used to receive Executive Diary every year from advertisers. These were daily planners to record my appointments by the hours. In the 1990s, I started using Filofax personal organiser. It was made of calf leather. I would buy refill of the calendar when the year came to an end. In mid-1990s, I had a Casio Digital Diary with just 128 Kbytes of memory space. In early 2000s, I had a Palm Personal Digital Assistant (PDA). These PDAs were a rage then until the mobile phones came onto the scene. Nokia mobile phone was the leader in smart phones space in 2000s until Apple’s iPhone took over in late 2000s. I had the iPhone 3G in 2008 and am still using iPhone for organising my contacts and calendar of appointments and events. Over a span of 50 years, we see the evolution of keeping diaries from paper-based Executive Diary to electronic diaries packed into smart phones. Disruptive technologies have taken over our lives. Old products faded away and we are forced into newer and technologically advanced products. The Baby Boomer generation adapts to these changes and you can see them swiping their smart phones in public places.
