Their job is so easy.

and their book will be useful for most of the people who bought the iPhone X!

Who buys such a book??? The iPhone X is so self explanatory

I do not understand books like this ...
Just like, window books on how to use windows, or Linux, or MS Office, or whatever useless looking books are out there ...

What kind of person pays money for it, reads is ENTIRELY (often multiple 100 pages) and after that say "I am smarter now" or "cool, now I know what I am doing"??

I don't get it ... Just waste of wood in my eyes. They should not had that tree chopped :-(

PS:
There are books out there which make totally sense and which are useful af. Not talking about those ...

iPhone x for homeless pls
