According to foreign media reports, Amazon released the Kindle Fire last Wednesday, the tablet computer market war started officially. The previous tablet computer market can be described as the world of iPad, it only has published more than a year, but the majority of consumers believed that it has become a mainstream product, its sales was to reach 30 million units and accounted for more than 40% of the share. Although there are some slightly competitive products, such as Samsung Galaxy Tab, as of last Wednesday, there are no real rival to Apple's products. However, this seems to have come to an end, because the Amazon officially released Kindle Fire and also it has become a strong challenger to the ipad. Some proponents of the Kindle may be pointed out as early as in 2007, Amazon entered the tablet computer market, but the Kindle is not a tablet computer in the true sense. It is considered a class of electronic information equipment that well reflects the functions of read and display e-book. The Kindle Fire is very different from the past Kindle products. It not only has a color touch screen, but also can play video files and run applications. What is more, there is a custom Google Android operating system that can connect to wireless networks. It also has self-designed the Silk web browser. It should be noted that Kindle has better performance than the ipad in terms of conversion. Kindle does not need a dvd to ipad for mac converter to convert suitable video formats, we all know that ipad can not copy dvd to ipad directly, but Kindle Fire can do this. However, the price was only half of the most basic configuration iPad 2, $ 199. Fire is being marketed to American from the November 19. According to projections, Amazon will be done trading losses this time. Fire is different from Apple products. It is mainly profit from the contents, that is, through books, music, videos and other products to make money. Although Apple also sells the content products, such as the iTunes store, its profit was lost to the hardware. Amazon's Web "cloud" has a lot contents on the product, Besides, its purchasing and ordering system are also very easy to operate. If the user experience of the Fire is proved to meet consumer expectations and still maintain the existing price, it will inevitably impact on apple ipad. So apple ipad is bound to be forced to lower their price, thus affecting profitability. Analysts will look forward to the next battle of two giants, Apple and Amazon. In fact, Apple and Amazon are trying to achieve one goal: to enable consumers to lock down their systems. Through iTunes and App Store, Apple is to ensure the Apple devices that are authorized to sell, however, Amazon do is more refined. The memory of Fire is only 8GB, so most of the contents that users used will come from its cloud storage. In this sense, Fire is a network device.
