Tablet shipments will surpass total PC shipments in the fourth quarter of 2013 (Q4 2013), forecasts IDC.
Tablets and smartphones will contribute 16.5 percent and 70.5 percent respectively to the worldwide smart connected device market by 2017, according to IDC Worldwide Quarterly Smart Connected Device Tracker.
The total PC sales are expected to drop to 13 percent by 2017.
This year, the global smart connected device, which includes PCs, tablets, and smartphones, is set to be US$622.4 billion and out of this US$423.1 billion will come from the smartphone and tablet segments collectively.
"At a time when the smartphone and tablet markets are showing early signs of saturation, the emergence of lower-priced devices will be a game-changer," said Megha Saini, research analyst with IDC's Worldwide Quarterly Smart Connected Device Tracker.
Continued growth is expected for tablet shipments and their growth will surpass total PC shipments on an annual basis by the end of 2015.
Strong growth is also predicted for smartphones that will continue shipping in high volumes, and surpass 1.4 billion units in 2015. Globally, smartphones will account for 69 percent of all smart connected device shipments in 2015.
The IDC tracker also predicts the global smart connected device market to exhibit double-digit year-over-year growth of 10.6 percent this year. This growth will slowly taper to reach 3.1 percent in 2017 indicating the growing impact on the market due to low-cost smartphones and the white box tablet market.
The average selling price (ASP) for the collective market will be driven by reasonably priced smartphones and tablets as consumers are no longer eager to spend on more expensive PCs.
"The device world has seen several iterations of cannibalisation impacting different categories, with the last few years focused on tablets cannibalising PC sales," said Bob O'Donnell, program vice president, Clients and Displays. "Over the next 12-18 months, however, we believe the larger smartphones, commonly called 'phablets', will start to eat into the smaller-size tablet market, contributing to a slower growth rate for tablets."
