Amazon, the e-retailing gaint, has unveiled three new Kindle Fire tablets at an event in California. Jeff Bezoz launched the new product at a launch function in California. The Kindle Fire HD comes in two options: with a 17.8 cm screen or an 8.9 22.6 cm one. That pitches the latter directly against Apple's slightly larger iPad, the bestselling tablet.
The HD models feature stereo speakers, an HDMI port - making it easy to connect to a television - and a laminated touchscreen to reduce glare in sunlight. They are powered by a processor made by Texas Instruments. In addition, they contain two wi-fi antennas and Mimo (multiple-input and multiple-output) radio wave technology to improve their connection to the internet. The bigger model can be bought with 4G connectivity at a higher price in the US.
