With the birth of a series of new products such as smart glasses, smart watches, and even drones, four heavyweight companies such as Apple, Google, Amazon and Microsoft have entered the battlefield of smart hardware devices: competing for mobile Internet and smart devices. The entrance, integrating systems, platforms and services as much as possible, embedded in the daily lives of users. The four giants have their own characteristics. Apple's advantage lies in the complete ecosystem of hardware, software and services. Microsoft's PC operating system dominates the world, Google is the leader of search engines, and Amazon has built powerful commodity big data. The four companies are currently in the field of intelligent hardware devices. Apple has a unique advantage in the field of intelligent hardware. Not long ago, the iphone6 ​​plus, a large-screen smartphone, was launched, which quickly set off a wave of market rush, followed by a series of new iPad Air 2, iPad mini 3 and OSX Yosemite. And launched the company's first wearable Apple Watch, in order to lead the wearable market trend. At the same time, Apple completed the unification of content between iOS and Mac OS through iCloud, achieving Apple's cross-platform experience. After launching the Android system, Google launched Nexus series mobile phones, Android TV, Google Glass and other hardware products. Of course, Google is also almost persistent in software services - Google did not make smart watches, but released can be applied to smart watches. The Android Wear system on the Internet allows other vendors to develop hardware, and smart phones from companies such as Samsung and Sony use this system. In addition, Google is developing driverless car projects, drones and Nest smart home products. Another smart hardware layout is Amazon. In the past nine months, Amazon has released three hardware devices: smart TV set-top box, smartphone Fire Phone and mobile payment device Local Register. In addition, Amazon is also developing drones and investing millions of dollars in its original video content business. Software giant Microsoft is the slowest hardware. In the process of combating iOS and Android, Windows Phone system is still struggling with the remaining 10% of the two platforms. In terms of hardware, in addition to its own three-generation Surface tablet, one of the most important measures is that in 2013, Microsoft made up for the competition on low-end and mid-end smartphones by acquiring Nokia's mobile phone business. However, the success of the Microsoft Xbox game console business is surprising, and it has won people's sympathy for Microsoft hardware layout. Apple started with hardware, and Google, Microsoft, and Amazon expanded from software to hardware. This will be a brutal struggle to invade and confront each other on equipment, services and platforms, but no one knows who the winner is.
