"Chaplin’s Law: every eventual hand-held device has shrunk from an earlier portable incarnation, one that had to be borne by two hands, if not an arm or two flung companionably round it." The magnifying glass - icon of detective fiction, daily tool of jewelry appraisers, and source of the modern symbol for 'search' - did not have that progression. Nor did writing utensils. I have a pen in my pocket right now. Overall though, an enjoyable read.
