Kobo Aura One

Nathan Spendelow looks at one of the strongest Kindle rivals we’ve seen in years

Amazon’s new Kindles might not command the headlines as they once did, but the retailer continues to sell e-readers by the bucketload and is more dominant in the sector than ever.

Kobo, however, is keeping up the fight and its latest offering, the Aura One, is a premium device with a generous 7.8in screen that has its sights set firmly on Amazon’s Kindle Voyage and Kindle Oasis.

With such a large screen, the Kobo is closer in size to a small tablet like the iPad Mini 4 than a standard e-reader. This has the advantage of fitting more words per page, providing a less cramped read. On the other hand, it’s significantly more cumbersome than the smaller 6in Kindles and is heavy for an e-reader at 230g.
