Research firm IDC is out today with its latest report on the smart-connected device market, and it includes worldwide shipments of desktop PCs, notebook PCs, smartphones, and tablets. IDC predicted the market in total grew 29.1-percent year over year in 2012, crossing 1 billion units shipped and hitting a total value of $576.9 billion. According to the report, Apple significantly closed the gap on Samsung during the last quarter of the year. It jumped from 15.1-percent in Q3 to 20.3-percent of unit shipments in Q4 2012. That brings the company up right behind market leader Samsung, which dropped slightly from 21.8-percent to 21.2-percent in the fourth quarter:

Looking specifically at the results for the fourth quarter of 2012 (4Q12), combined shipments of desktop PCs, notebook PCs, tablets, and smartphones was nearly 378 million and revenues were more than $168 billion. In terms of market share, Apple significantly closed the gap with market leader Samsung in the quarter, as the combination of Apple’s iPhone 5 and iPad Mini brought Apple up to 20.3% unit shipment share versus 21.2% for Samsung.

Apple’s increase is likely thanks to strong iPad and iPad mini sales, as growth in the market was “largely driven by 78.4-percent year-over-year growth in tablet shipments.” IDC expected tablet shipments to outgrow desktop PCs by the end of this year, while the tablet market could surpass the portable PC market in 2014 and provide Apple with even more opportunity to outgrow Samsung for total connected smart device shipments this year and next: expand full story
