Shipments of PCs are definitely growing, for the first time in six years. Market research firms Gartner and IDC both agree that the PC market grew in the second quarter of 2018, with IDC claiming an increase of 2.7 percent and Gartner recording a more modest 1.4 percent of growth. IDC first revealed the PC market was starting to flatten and show potential growth last year, but both Gartner and IDC track PC shipments differently.

IDC’s data crucially includes Chromebooks and excludes Windows tablets including devices with a detachable keyboard like the Surface Pro. Gartner counts Windows-based tablets as PCs and excludes Chromebooks or any non-Windows-based tablets. Chromebooks appeared to be powering some PC growth last year, but now that Gartner is tracking overall growth it’s clear this is also from regular Windows PCs or Macs, and not just from Android tablets or Chromebooks. This is the first year-over-year PC shipment growth since the first quarter of 2012.
