The death of Steve Jobs prompts me to recall that 20 years ago, when I had to travel on business, I sat relaxed on the train knowing that no one could contact me.
I did not have my peace disturbed by hissing noises from nearby earphones, overhearing the utterly uninteresting phone conversations of nearby and not so nearby travellers and the clattering of laptop computers and flickering coloured lights.
I might write a few notes in my notebook regarding meetings to come, or meetings just attended. I could write minutes and notes for my secretary to type for me.
My boss did not expect me to contact him until the next time I was in the office, unless some extraordinary, unexpected thing had happened.
Oh, happy days.
