The platform of leadership is based on PalmSource, Microsoft, RIM and Symbian, etc., but these platforms have excellent disadvantages. Enterprises should consider reducing the number of platforms they support, because they all require considerable investment to develop specialized technology and tools to maximize these properties. Symbian uses voice applications as cores: Symbian is the leader of this way, they emphasize the integration of voice function and data and voice function. The most popular smart phone in the sales market is based on Symbian. Symbian's licensing range includes a wide range of equipment varieties: such as a telephone with a micro-keyboard, a phone input by a stylus, and a phone equipped with a QWERTY keyboard. NOKIA, as a giant that leads the global mobile phone field today, is also the powerful driving force of the Symbian platform. RIM uses email as the core: In this regard, the RIM platform proved to be the most shining star in the wireless data stage. He uses a desktop calculation mode to closely process data. Microsoft and PalmSource are used in universal mobile data as core: Palmsource Treo 600 Phone PDA is recognized as the best performance in similar products, he can balance the huge installation load brought by palm applications, and this characteristic makes it possible to achieve Off-the-shelf to meet user needs is no longer far away. Microsoft provides the most powerful support for companies in its Windows Mobile OS, especially Microsoft-Centric. In addition, Microsoft OS also has powerful network functions. Now Microsoft and PalmSource have turned their focus from the PDA to the mobile phone market. Linux mobile devices and server seamless integration: Now useful for the latest versions of embedded computing, such as PDA and phone, etc., is Kernel 2.6, which is a powerful operating system with enhanced real-time performance, and for microcontrollers. I / O flexible support, as well as large storage features. Although he now has almost no market share, it is generally believed that Linux is likely to be a heavyweight role in the future, especially as the powerful computing power of the hardware platform. There are already some vendors to start to make actions: Motorola is only one of the manufacturers who provide Linux smartphones; while Sharp Zaurus PDA also uses Linux. On the other hand, Linux has obtained a larger server market, especially some of the seamless expansion of server data, and a comfortable development environment created for organizational and ISV (Independent Software Vendors, Independent Software Vendors). . In fact, in the end, whether mobile phone manufacturers such as Motorola, or Linux providers such as Red Hat, they will lead this market together. For users, in addition to paying attention to the market changes, if there is how many users choose Linux as the platform they use, it is still necessary to depends on the application that users want to run, and existing backend systems, not individual technology. Advantage.
