In our family it’s mostly Kindle these days. We share an account, and read on various electronic devices. This works great; recently my wife and I read the Inspector O novels, while my 12-year-old and I read The Hunger Games.
This works because Amazon doesn’t mind multiple devices at once having access to a book; and because our “Amazon identity” is a lightweight shopping-context thing, not like a “This is really me” Facebook or G+ identity. It requires trust; anyone in the family could go and charge anything Amazon sells to my credit card. But you can have that, at the family level.
I will buy a certain number of e-books, even while grousing about the price, but it’s really important that the natural unit of book purchase is the household not the individual. Or put another way, book-reading is essentially social; the original viral media, and what family doesn’t pass viruses around?
I probably shouldn’t write this; somewhere a publishing executive is reading it and thinking “They’re sharing books?! Shock! Horror! We’ll make them each buy their own copy! Ka-ching!!
Let’s try to keep the go-back-to-paper option alive, maybe.
