The only reason to pack a Kindle is the superior reading experience compared with the Kindle app on your smartphone and, in some instances, a paperback or hardback book. And the more expansive 6.8-inch e-ink makes reading on the e-reader better than before. As mentioned above, the bigger screen allows you to fit more onto every page. But it's not just words, if there are illustrations in the book, they're much clearer on the new display.

Kindle Paperwhite review: Amazon has built the last e-reader you'll ever buy

The warm light adjusts the colour temperature on-screen, which reduces strain on your eyes late at night. There are 24-levels of warmth, with anything under five barely visible and the top-end of the slider transforming your book into a yellowing centuries-old scrap of parchment. This can be manually tweaked from the quick settings menu, or can be scheduled on a timer, based on your own preferences. Amazon has also released a pricier Kindle Paperwhite Signature Edition, which adds a sensor to automatically tweak the brightness of the display to the lighting around you. While that's useful, the latest version of the Kindle software makes it ridiculously easy to quickly access the slider for brightness and warmth, so it's far from an essential feature.

Not only is the e-ink screen on the new Kindle Paperwhite bigger, but it's also faster than previous generations. Amazon says this results in 20 percent faster page turns. In our time with the Kindle Paperwhite, the e-ink display always felt incredible responsive and fast the standards of e-ink displays, of course. If you're expecting the sort of performance you'd see from an OLED panel on a modern smartphone, you're going to be sorely disappointed. But flicking between pages is fast enough that you'll never be taken out of what you're reading.
