It's 2018, not 1918. Don't slough off "old people" so easily. I'm 76, and if I had a Note 9 and a week, I could probably write the book. I can also look things up on Google - there's even a Google search bar in my Firefox browser (the one I'm typing this on).
Remember, some of us "old people" are the ones who designed the technology you young kids (anyone under 60) are using today. When I was born, no one had TV - it didn't come out until 4 years later, and a simple 7" monochrome set cost about what a 55" set costs today.
And reading the book only teaches you about the Note 9 - learning about Google (or your choice of search engines - or that there is a choice) teaches you ow to look up anything you need - Note 9s, medication interactions, our anthropological history - everything. "Give a man a fish ..." Write a book on how to find the information and you help a lot more people (and probably sell a lot more books - not many people "who don't use o.k. Google, or look up things on Google" go for flagships like a Note 9). People on a fixed income either use Lifeline (and are happy to have a phone they can carry with them) or look for something like Consumer Cellular and a $10 phone. But if they can use a search engine - wow! the whole world is open to them. And everyone who doesn't know to look it up on Google can use a book like that. (How do you look up "how do I turn off notifications on a note 9"? Just leave off the "how do I" part. Their parser is pretty good.)
