PC sales were up year-on-year in the second quarter of 2018, the first such increase since the first quarter of 2012. Market research firms Gartner and IDC both reported growth in the market, of 1.4 and 2.7 percent, respectively.

The two companies track numbers differently: Gartner includes Windows-based tablets but excludes Chromebooks and non-Windows tablets, whereas IDC includes Chromebooks but excludes all tablets, even those like the Surface Pro that are used and sold as PCs.
