BEIJING, July 27 (Xinhuanet) -- Amazon.com’s e-book reader Kindle 3G with special offers is now the company’s top-selling e-book device, according to media reports on Wednesday.Amazon revealed in its quarterly earnings report that the ad-supported version costs 139 U.S. dollars,  50 dollars cheaper than the comparable Kindle 3G, and costs the same as a Kindle with Wi-Fi connectivity. Many believe Kindle is the most popular dedicated e-book device on the market today.The advertisements will appear only in screensavers (which appear when the reader is in an idle state) and at the bottom of the home screen, so they don’t interrupt readers.“Since AT&T agreed to sponsor screensavers, Kindle 3G with Special Offers is now our bestselling Kindle device,” Amazon’s press release said.Having zoomed past the earlier Sony Reader, and kicked off a wave of competition including the Barnes & Noble Nook and the Kobo E-Reader, Kindle is believed the most popular dedicated e-book device on the market today.

BEIJING, Aug. 13 (Xinhua) -- The quality of the products China exported to the European Union (EU) improved during the first half of this year due to strict quality control measures, according to quality control authorities.The number of quality complaints made by the EU regarding Chinese imports declined by 45 percent in the first half of 2011, according to the General Administration of Quality Supervision, Inspection and Quarantine (AQSIQ).The administration attributed the improved quality to its nationwide crackdown on counterfeited and substandard products.The administration launched a nationwide quality checkup in the first half of this year. Of the 4,815 batches of products that the quality control authorities checked between January and June, just 9.4 percent failed quality tests, 1.7 percentage points lower than that of the same period of last year, according to the administration.A total of 218,000 counterfeiting cases have been investigated so far this year, involving goods worth a total of 9.5 billion yuan (1.49 billion U.S. dollars), the administration said.

CANBERRA, Aug. 31 (Xinhua) -- Australia's new chief medical officer, Professor Chris Baggoley, on Wednesday said Australian should not be worried about reports that a mutant strain of the deadly bird flu virus is spreading across Asia and beyond.On Monday, the UN's Food and Agriculture Organization (FAO) said a mutant strain of the deadly avian influenza virus was spreading in Asia and issued a warning that the bird flu could spread from poultry to humans. It urged "heightened readiness and surveillance" as the mutant strain posed "unpredictable risks to human health."But Professor Baggoley, who took office on Tuesday, said Australia is well served by strict testing and customs regimes, adding that avian migration patterns also mean infected birds are highly unlikely to arrive in Australia."I don't think we should be worried," Prof Baggoley told Sky News."The country and the Australian government is certainly vigilant in relation to bird flu."Prof. Baggoley insisted the H5N1 virus remains overwhelmingly a disease of birds and it is very uncommon for humans to catch it. It is also exceedingly rare for humans to spread it among themselves.He said that even if bird flu did arrive and affected humans, Australia is ready to respond to any new and significant developments in bird flu."Australia tests migratory wild birds, looking for H5N1, and has been doing this for some years and has never found it," he said."On the human side of things, Australia has been preparing for a possible outbreak of H5N1 since 2004."We've got the laboratory capacity to diagnose influenza; we've got arrangements in place for a rapid production of an H5N1 vaccine for humans, and we've got ready access to antivirals."There have been no outbreaks of bird flu in Australia to date.The UN said the latest human death from bird flu occurred earlier this month in Cambodia, which has registered eight cases of human infection this year, all of them fatal.H5N1 has infected 565 people since it first appeared in 2003, killing 331.

SAN FRANCISCO, July 7 (Xinhua) -- Apple announced Thursday that over 15 billion applications have been downloaded from its App Store by more than 200 million Apple mobile devices users worldwide."Thank you to all of our amazing developers who have filled it with over 425,000 of the coolest apps and to our over 200 million iOS users for surpassing 15 billion downloads," said Phillip Schiller, Apple's senior vice president of worldwide product marketing, in a statement.Launched on July 10, 2008, Apple's digital application distribution platform has been growing at a fast speed. It took nine months to hit one billion downloads and five billion in June 2010. In January, Apple gave a 10,000-U.S. dollar App Store gift card to a user who downloaded the 10 billionth application.In Thursday's statement, the Cupertino, California-based company said it had paid developers 2.5 billion dollars to date.Apple's mobile market place is far ahead of Google's Android Market. At its annual I/O conference in May, Google said there had been 4.5 billion app installs so far. But Google said the growth of its mobile operating system and applications is accelerating with its store hitting another billion downloads every 60 days.Currently, Apple is in a legal battle against Amazon over the use of "Appstore," which the online retailer launched in March to sell mobile applications to Google's Android platform users.On Wednesday, a federal judge denied Apple's request to immediately stop Amazon from using the term "Appstore."Meanwhile, Amazon, Microsoft, HTC, Nokia and Sony Ericsson have filed complaints against Apple in Europe, seeking to get Apple's trademarks for "App Store" and "Appstore" invalidated.
