Amazon Kindle e-readers have been the leader in the US. Kindle Store offers an astonishing choice of books, magazines, newspapers and blogs. In Kindle you won't see this in the dark if you want to put it to sleep before bed. You can't see the screen in the dark, so you won't see the offers. They show up in the same paper format that your e-books show up in, so it's a matte paper screen, essentially.
