If you are bitten by the reading bug and electronic books are your thing, Kindle devices are for you. Kindle is a series of modern electronic book readers designed and sold by Amazon. The e-books offered cost significantly lesser than the hard copy edition of the books. Users can browse through the Amazon store and buy e-books. Apart from e-books, one can read newspapers and magazines as well. A Kindle has to be charged very rarely and all of your reading material will be at the tip of you fingers. Though the Kindle is the first choice for any book lover in terms of electronic book readers, it can be a little expensive. The company introduces new models to the series every now and then. When users upgrade to the latest version they sell the one they had been using. This opens the door to a market of used and refurbished kindle devices. The used and refurbished devices can be bought at a significantly low price. Difference between used and refurbished The terms used and refurbished are used interchangeably on several occasions. However, they are not the same. The major difference is that refurbished items are professionally tested and repaired.
