Hands-on review: Kobo Aura One

Kobo's latest premium device is the phablet of the ereader world. It feels huge in the hand right now, but it may be that in five years time a 7.8-inch screen ereader will be the norm.Every ereader you can buy right now – including all four products in the ever popular Amazon Kindle range – boasts a 6-inch screen, but the Aura One wants to make a major change by offering a larger alternative.That 7.8-inch screen will feel huge to you if you've been using a Kindle or any other ereader
