Because I’ve spent most of my working life writing about technology, people expect me to be among the first to adopt every new device and application that hits the market. It’s because I follow tech trends closely that I’m seldom an early adopter. I know, for instance, that the first generation of any tech product is likely to be followed very soon by a new version with more features, fewer flaws and a lower price tag. Most people understand my views on adopting new technology. Still, I get puzzled looks when I tell someone that I’m not one of the 500-million-plus members of Facebook.
