Amazon's Kindle family has been famously associated with the term "e-book" ever since the company realised that digital sales of novels were going to take off. The original Kindles came with buttons and a QWERTY keypad for note-taking and worked only on Wi-Fi. Later models included 3G for downloading books on the go and also were ad-supported, a move by Amazon to keep the cost of the tablets down so that people could buy them cheaply.
Recent upgrades to the family were touch-capable screens for the regular e-Ink readers and the Kindle Fire, Amazon's first Android-based tablet that used the same hardware found in the Blackberry Playbook to provide a decent tablet experience in the $200 price range. And now, a new onslaught of e-Readers from the media giant looks set to take on the world again.
