Amazon still has a lot of faith in its Kindle brand, and will be releasing an all new model very soon.
The Kindle Fire HD 8 Reader's Edition is a special version of the tablet which comes with features that will appeal to readers. So you get a glorious eight inch screen with a new Blue Shade option to begin with. This limits the amount of light the screen is giving off, which makes it much easier to read from in very low light conditions. This also reduces glare, which could help you get to sleep easier.
Other extras include a very fine leather cover and a years access to Kindle Unlimited. This is a subscription service which lets you read as many books as you want every month for a set fee of $10. Only certain titles are represented but with over a million so far there should be plenty for everyone. That subscription alone saves you $120, so this could make a great present for the avid reader in your life.
The tablet iself is a versatile beast, with an 8 inch screen, front and rear cameras and expandable storage up to 128 gigs. You can also use it to easily listen to books, thanks to the Audible service - the tablet comes with a 30 day free trial.
The Kindle Fire HD 8 Readers Edition is only available on Amazon.com right now but hopefully it will come to other locations soon.
