After a few months, Amazon's 7-inch tablet computer Kindle Fire has come on stage finally. Compared with Apple ipad, this tablet computer is much more like Nook Color and we can hardly see any mark about Android. Apple's entry-level iPad sell at $ 500, which is a very stubborn problem to other tablet computer manufacturers. Kindle Fire reduced the tablet computer's "threshold” again, it is reported that Kindle Fire will sell at $ 199. Some analysts believed the price of $ 199 of Kindle Fire will become a killer for Apple iPad, but it is estimated that this will not happen. Apple launched its products and does the opposite: driving hardware sales by low-cost songs, podcasts, videos and applications. Its profit margin was higher, and has achieved unprecedented success. So, are the Android tablet fans who want to buy a lower- price tablet computer attractive to Kindle Fire? Or Kindle Fire will attract Kindle e-reader users who want to use more features. According to industry projections based on early sales figures, the sales of Kindle Fire will be lower than expected. According to the communications industry analyst firm Current Analysis analyst William Holden said: the launch of Kindle Fire is a tool that help Amazon to attract customers and then make more profit by its service and content. "However, from a hardware perspective, compared with the other tablet computers, Kindle Fire does not constitute an overwhelming superiority. Although it is equipped with dual-core processor, 512MB memory and 8GB storage capacity, but it lacks some based equipments, such as camera, Bluetooth, microSD slot, GPS and so on some key functions of traditional Tablet computer. Even compared with the ipad, it only can support flash formats, other video formats still not be played on it like the ipad, for the ipad only can support mov file and mp4, If you want to play other video formats on the ipad, you need to convert it into a suitable format by using a dvd to ipad mac converter. Kindle Fire is no exception. Early positioning of the tablet computer market is not just a show, the tablet computer manufacturers need to urge developers to create necessary applications to attract customers, and developers do not want to waste time on unattractive device. Amazon's Kindle Fire will be the first tablet computer that is a positive form of competition to Apple iPad. In my opinion, Apple iPad still has a lot of improvements, for its compatibility, Apple has several different system and also they are not compatible, if you want to transfer some files from one to another, you need an ipad to computer transfer.So I think that if Apple can solve this problem, it will greet more bright development future.
