The Signature Edition also has wireless charging, and Amazon offers some simple and elegant charging stands to prop your Kindle Paperwhite next to the bed and keep it charged. You can get 12 weeks of reading if you're a casual, half-hour a day reader, but if books are your hobby, you want to charge more often.

Among the new Kindles is a redesigned Scribe, which comes in classic black or a flashy metallic jade and won't be officially available until Dec. 4. The new Scribe's screen got a makeover with added white borders to give it a more notebook-like feel. If the new model is anything like the current one, I'm excited to see what it offers.

The Kindle Paperwhite Signature Edition is currently priced at $154.99, down from its list price of $199.99 which means you save $45 during Black Friday (until it runs out of stock). This model features a 7-inch glare-free display that provides a comfortable reading experience in any lighting condition.
