iPad 2 Rival Alert : Kindle Fire Remains Best-Selling Product at Amazon

Amazon revealed yesterday that it has been selling more than one million Kindle devices every week since the end of November, with the Kindle Fire being the star of the show.

The company said that its colour tablet has been the best-selling, most wished for and most gifted product on Amazon.com ever since it was put on preorder more than three months ago.

Amazon also revealed that sales of the Kindle Fire are increasing week on week, with the company adding, it is "building millions more to meet the demand".

It also highlighted the interesting fact that many customers are buying two kindles, the more expensive Kindle Fire and either a Kindle or a Kindle Touch, indicating that customers consider both products to be significantly different.

The Kindle Fire - which costs $199 in the US - shares many common features with the Blackberry PlayBook tablet, as well as the Kobo Vox and the Barnes & Noble Nook Tablet.

It comes with a dual core TI OMAP chipset clocked at 1GHz, 512MB RAM, 8GB onboard storage, a 7-inch 1024x600 pixel capacitive touchscreen but no camera, no microSD card slot and a closed Android-based operating system.
