Tablet shipments will surpass total PC shipments (desktop plus portable PCs) in the fourth quarter of 2013.
PCs shipments are still expected to be greater than tablet shipments for the full year, but IDC forecasts tablet shipments will surpass total PC shipments on an annual basis by the end of 2015.
Smartphones will continue to ship in high volumes, surpassing 1.4 billion units in 2015 and accounting for 69 percent of all smart connected device shipments worldwide.
“Introducing new handsets and tablet devices at cheaper price points along with special initiatives like trade-in programs from Apple and BestBuy will accelerate the upgrade cycle and expand the total addressable market overnight,” said Megha Saini, Research Analyst with IDC’s Worldwide Quarterly Smart Connected Device Tracker.
IDC expects the lower-cost devices to drive interest worldwide and help to spark uptake among first-time buyers in commercial sectors like education.
A new round of device cannibalization is also expected to kick in, but this time with large-screen (5+ inch) smartphones beginning to impact the smaller (7-8 inch) tablet market.
Over the next 12-18 months, the larger smartphones or phablets will start to eat into the smaller-size tablet market, contributing to a slower growth rate for tablets.
IDC says the worldwide smart connected device space shipments surpass 2 billion units by the end of 2015 with a market value of $735.1 billion.
In terms of device mix, total PC shipments accounted for 28.7 percent of the smart connected device market in 2012 while tablets accounted for 11.8 percent and smartphones for 59.5 percent.
By 2017, total PCs are expected to drop to 13 percent, while tablets and smartphones will contribute 16.5 percent and 70.5 percent respectively to the overall market. The shift in demand from the more expensive PC category to more reasonably priced smartphones and tablets will drive the average selling price (ASP) for the collective market from $462 in 2012 to $323 in 2017.
