Amazon brought out its first Kindle in November 2007, and after 2 years released its second version of kindle, which had two additional features, more storage space and an option to read out aloud to the reader. This version was slimmer and upgraded version to be able to read the PDF files. In 2010 Amazon released a new version which had 2 variants- a wifi enabled and the other 3G enabled.
