Query: Surprisingly entertaining

The Box is a history of shipping containers, which I began reading because the author, Marc Levinson, is a friend. Knowing Marc I was not surprised at the depth at which he has handled the subject (is there any more to be said?) but quite surprised to find it was interesting and entertaining. The development of the container (1950s to the present) has changed our lives in ways which I was oblivious. It is a (maybe the) reason that New York City has lost its shipping industry, the reason that the office bulding I work in (former Cunard lines shipping office) now houses a law firm, the reason that I see the giant cranes in Elizabeth New Jersey out my window, behind the Statue of Liberty. It is also the (a) reason that my shirts are made in Malaysia and my underwear in Vietnam. It's fascinating to realize that major changes in our lives are caused by the relatively unpublicized adoption of relatively low-tech technology.
