During the next five years, consumers will add more devices to their personal portfolio rather than consolidating it, according to Gartner, Inc. (www.gartner.com). By 2018, a consumer in a mature market will use and own more than three personal devices, says the research group. 

Gartner estimates that in 2016, the installed base of devices will total 7.8 billion units (including wearables, phones, tablets and PCs) and is on pace to reach 8.3 billion units in 2018. 

"The combination of the high level of adoption of technology, the availability of faster networks, and decision making becoming increasingly dependent on real-time information, will undoubtedly lead to more devices per user," said Anshul Gupta, research director at Gartner. 

Gartner expects mature market users to use three to four personal devices from a mix of "main" and "niche" devices. Main devices will include smartphones, tablets, convertibles (two-in-one devices) and notebooks, and will contribute to more than two devices per person at any time. Niche devices will include a growing range of wearables such as smart watches, health bands, smart glasses and new types of connected devices such as smart cards, e-readers and portable cameras.
