1. Amazon Kindle Paperwhite
From £109, amazon.co.uk
This is Amazon’s best e-ink reader yet. It’s great in the sunshine, but what about indoors, when it’s not well-lit, you say? This screen has a front light which illuminates the page, and doesn’t tire the eyes like backlit screens do. You’re tied into Amazon’s bookstore, just as rival ereaders lock you into their stores, but note that you can read Amazon books on iPad, iPhone, iPod, Android phones and more thanks to apps for the appropriate machine. Handy if the Paperwhite runs out of juice, though frankly it lasts for weeks (less if you have the light on all the time). Like most other Kindles with e-ink, this has a six-inch display.
