It’s $70 cheaper than the Kobo Libra Colour — my top non-Amazon e-reader — yet offers many of the same features, including a spacious 7-inch 300pi display with rich contrast levels. Like the Kobo Libra Colour, it’s capable, for example, of solving math equations for you. If you want a color screen and want to stick with Amazon, the Colorsoft Signature is your best option. Otherwise, I’d still recommend the Kobo Libra Colour to everybody else. However, similar to the Kobo Libra Colour, this ad-free model offers physical-page turning buttons and supports note-taking.
