> And what's so special about books in particular, anyway?

About just every end of day, when I go to kiss my wife and my kid (11 years old) when they go to their respective beds, they're both reading a book.

A book is compliant with a "no screens before bed / no screens in the bedroom" policy and that's very particular.

It's also a real physical item that shall working without needing to be recharged, that shall keep working when the Internet is down, that won't disappear when the site is blocked for whatever reason, etc.
