Tablet sales are flat and PC sales are down, but IDC reports that Chromebook sales have fallen the hardest of all, with an incredible 51.4 percent year-over-year decline.

So is this game over for Chrome OS? IDC says no.

“While Chromebook shipments have trended down in the past few quarters, there’s still [an] opportunity to be had as the pandemic has brought about positive changes to Chrome adoption,” IDC’s Jitesh Ubrani says. “The need for remote learning accelerated schools’ plans to reach a 1:1 ratio for PCs to students and this ratio will likely continue to hold in the future and even if PC shipments decline in other categories, Chrome will continue at these elevated levels.”

The Chromebook market is tiny, based on IDC’s numbers, with just 6 million units sold in the second quarter, and not all of those sales went to end users yet. By comparison, IDC claims hardware makers sold 40.5 million tablets in the same time period.

And the top five Chromebook makers all experienced double-digit YOY unit sales declines. Dell is now the biggest maker of Chromebooks, with 1.5 million sold in Q2, a decline of 15.5 percent, and Acer is number two with 1.3 million units (down 28.9 percent). Lenovo (1.2 million, down 54 percent), HP (900,000, down 78.6 percent), and Samsung (400,000, down 57.3 percent) round out the top five.
