The Paperwhite has a 6.8-inch high-resolution e-ink display, which won’t show glare from the sun like the LCD screen on a smartphone or tablet. Reading on an e-ink display is also easier on your eyes. The Kindle is inherently a uni-tasking device — there are no apps, no web browser, no notifications — which makes it easier to concentrate on reading. It also allows the Kindle to last several weeks on a single charge, which is especially helpful if you want to read through an entire international flight. The best ebook reader deals
