As CES 2016 opens the device announcement floodgates consulting firm Accenture reports the results of a sobering global survey-- one showing customers are "much less inclined" to buy new technology in 2016.

The survey involves 28000 customers in 28 countries. It shows demand is sluggish, if not dropping, across all traditional categories, be it smartphones (2016 purchase intent rate 48%, down from 57% in 2015), laptops (30%), TVs (30%) and tablets (29%). Meanwhile supposed "next big things" such as smartwatches (13%), fitness monitors (11%) and personal drones (17%) fail to make much of an impression.

Ericsson's ConsumerLab presents the most important consumer trends for 2016 and beyond-- with futuristic predictions including internal sensors, printable foods and smartphones becoming essentially obsolete.

At its broadest the report represents 1.1 billion people across 24 countries, while at the narrowest it represents 46 million urban smartphone users in 10 major cities. In any case, here are the 10 trends it actually contains.

According to Gartner customers in mature markets do not plan to consolidate personal device collections-- instead more devices will actually be bought, bringing the number of devices per user to around 3-4 by 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," the analyst says.

Gartner predicts mature market customers will use 2 "main" and 1 or 2 "niche" devices in the near future. Main devices include smartphones, tablets, convertibles (aka 2-in-1 hybrids) and notebooks, while niche devices include wearables (smartwatches, fitness trackers, smart glasses), smart cards, eReaders and portable cameras.

IDC reports global tablet shipments are to reach 211.3 million units in 2015, a -8.1% drop following 3 consecutive quarters of declining WW tablet shipments in 2015.

However, while the device category appears to be on the wane the analyst points out at least one growth opportunity-- tablets with detachable displays.

"We're witnessing a real market transition as end users shift their demand towards detachables and more broadly towards a productivity-based value proposition," IDC says. "The proliferation of detachable offerings from hardware vendors continues to help drive this switch. We're starting to see the impact of competition within this space as the major platform vendors-– Apple, Google and Microsoft-- now have physical product offerings."
