&quot;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.&quot;<p>The magnifying glass - icon of detective fiction, daily tool of jewelry appraisers, and source of the modern symbol for &#x27;search&#x27; - did not have that progression.<p>Nor did writing utensils. I have a pen in my pocket right now.<p>Overall though, an enjoyable read.
