In November 2011, Amazon released the Kindle Fire tablet computer. This was the second best-selling tablet after the Apple iPad. It was built with Quanta computer and featured a 7-inch screen with a multi-touch display with IPS technology. The Kindle Fire had access to the Amazon Appstore as well as the Kindle store for e-books along with streaming of movies and TV shows.

It has a 6-inch screen, 212 PPI E Ink Pearl display (758×1024 resolution) with 4 LED’s built-in for illumination of the screen.

With the advent of Amazon, people preferred to buy books from the comfort of their homes. When Amazon released their Kindle e-readers, mortar bookstores faced huge losses. In order to survive this stiff competition, one of the popular mortar bookstores, Barnes and Noble released a cheap e-reader called NOOK® e-Reader. NOOK® e-Reader is supported on Android platforms and they have partnered with multiple third-party users and made it available on devices such as Samsung tablets and phones.

Currently, Amazon Kindle has a larger customer base due to their ease in use as compared to the NOOK®. Also, Amazon has a wide variety of cheap Kindle tablets and the customers can choose what suits them best.
