not on a Kindle. Amazon started as a book store

...without?

As cores também. No livro ainda temos menos cores, mais preto no branco e isso ajuda muito no foco e concentração

who's gonna tell him about printed advertisement. (usually found at the end/befinning of a book)

*without. My bad

Tbh I'm much more likely to finish a printed book than an ebook.lol I have a kindle color but jailbroke it to install KoReader & terminal. Been in the habit of trying to have a day or two a week with little to no technology....all analog.
