Good ebooks on just about any topic are widely available today. The Project Gutenberg itself contains about 21000 books, including the classics, and other books whose copyright has expired. The only problem is reading them, from the computer screen. With the new monitors it’s not too much strain on the eyes, but you get a stiff back and neck, if you sit continuously staring at it. If only there was some device roughly the shape and size of a book, which can display the ebook page by page, which you can read lying on your back, sitting, or any way you want, it would be easier. Sure, it can never match a real book, but it would be almost good enough. And when you finish reading a book, all you’ve got to do is upload the next one! A lot of paper can be saved.
