A color e-reader will display B&W content such as the content of an ebook at 300 PPI, but any color elements will only be at 100 PPI. This includes, cover art, PDF files, pictures and imagery of any kind. The Kindle shows all content on the screen at 300 PPI in black and white E INK. The Amazon ecosystem is deep and rich, but how does the overall reading experience compared to a color e-reader? Today, Good e-Reader has produced a video that shows how reading ebooks and PDF files is totally different on a black and white display vs color.
It has an excellent screen with 300 PPI, is waterproof and has Bluetooth for listening to audiobooks. The Amazon Kindle Paperwhite is one of the most successful e-readers ever and the 4th generation model has some big selling points.
