At the end of the Eastern Han Dynasty, the disputes between the princes and the chaos of the world were over. In various regions, zhuhou only needs to improve his own strength and occupy more land. However, among the many forces, only Cao, Liu Bei, and Sun Quan are superior to others in terms of capabilities, talents, and terrain. After a period of fight, other forces gradually disappear, and then form a three-pronged trend.
In the world of mobile phones, Symbian, which once integrated the mobile phone market, is now about to become the Chinese dynasty on the evening of Chinese. Now iOS, Android, WP7, BlackBerry OS, Web OS, brew, bada, meego and so on, many mobile phone systems are competing to divide the mobile phone market, are trying to improve their own technology, enhance their talent, in order to be unbeaten in the smart phone field. After 2010 disputes, the iOS and Android forces can claim the first two seats in the mobile phone world, which should be undisputed.
Now, the era of smartphones has come, and the smartphone market has been squeezing the PC market. Smartphones are gradually integrated with PC functions. In addition, smart phones are inherently portable and human dependence on mobile phones, in the next few decades, the occupation of the smart phone field will occupy more than half of the IT world. Microsoft innovated the WM system and launched a brand new WP7 to gain a place in the smart phone field. Due to many development bottlenecks of the Symbian system, Nokia has switched to the WP7 camp, using WP7 as its main smartphone system. With Microsoft's powerful technologies and Nokia's reputation in the mobile phone market, WP7 is bound to become a powerful force behind iOS and Android.
In this case, it will surely bring about the three powers of the smart phone era.
