Amazon’s best-selling Kindle, the Paperwhite, has also received some updates. It’s been given 25% faster page turns, which benefits the Kindle Library or the Store with a more responsive experience. It’s also been bumped up to seven inches but is still the slimmest Kindle on the market, with up to an impressive three-month battery life.

Amazon announced the launch of its first color e-reader, the Colorsoft Signature Edition. The tablet offers a 7-inch display without backlighting to keep it easy on the eyes with an improved page-turning response, better contrast, and more visual enhancements.

Joining refreshed Paperwhite, Scribe, and entry-level Kindle models, the Colorsoft brings a whole new dimension to Amazon's lineup of ebook readers. Read on for our first impressions of all four new Kindles.
