“eBooks save trees, eBooks eliminate the need for filling up landfills with old books. eBooks save energy, and transportation costs, and reduce the pollution associated with driving and flying books across the country and around the world, and then eBooks eliminate the problem of "unsold books", which are often shredded. In the Netherlands alone, more than one million books are shredded every year and transformed into toilet paper. ( A smart step, but still a waste of energy and resources.)”.
However, those readers are not free; you are going to spend a good amount upfront for a device like this. Therefore, eBooks have stories which are both eBook readers for free and spend money, but the story is cheap.
