When I hold my Kindle in my hand, I am deeply aware of how rich I am. For I hold thousands of books and can summon them at a touch, where my ancestors a thousand years past were illiterate, and the lords they served had to mortgage their second castle to afford a book or maybe two.
P.S. One of my readers cheekily wrote in to add, “It also hurts less when you fall asleep and drop it on your head,” and I can confirm that this is definitely true. I am still smarting from the time, years ago, when I dropped a hardcover The Lord of the Rings omnibus on my head when I fell asleep reading in bed.
