Amazon's best selling reader device, the Kindle is a thin electronic device used to download e-books and some magazines wirelessly and read them. Since its first launch a couple of years ago, two more versions of the Kindle e-reader have been released ( Kindle 2 and Kindle DX ), while the original version cannot be bought as new anymore. Just recently, 3g wireless coverage for the Kindle 2 model has been made available worldwide in over 100 countries
