Market research company IDC announced on Jan. 11 that the category of products that it refers to as “traditional [personal computers]” dropped 1.5% year over year during the fourth quarter of 2016 and by 5.7% over the course of the entirety of 2016. IDC said that the first quarter of 2016 was “still constrained by high inventory, free Windows 10 upgrades, and difficult comparisons to commercial replacements in 2014 that were fueled by the end of support for Windows XP.”
