It is amazing how recently everything changed. The first iPhone hit the planet a mere eight years ago and now all of humanity seems to have adopted the same cramped physical position: phone held at mid chest, head bent downward toward the screen, mind oblivious to any other stimuli whether one is sitting, walking or even driving a car. Twitter was a mere prototype in 2006; now many of us have become adept at saying all we have to say in 140 characters. It was only back in the 1990s when e-mail began to fill our work days, first with a flood of spam, then with a mountain of actual work-related messages that few of us ever dig all the way through. Apple is now the world's biggest company, but the first Apple Macintosh computer was put on the market just 31 years ago in 1984 -- the same year Mark Zuckerberg, the founder of Facebook, was born.
