IDC analysts estimate close to 2 million Chromebooks were sold in the US in Q1 2016, versus 1.76 million Macs.
IDC estimates Apple's US Mac shipments to be around 1.76 million in the latest quarter, meaning Dell, HP, and Lenovo sold nearly 2 million Chromebooks in Q1 combined. Chromebooks have been extremely popular in US schools, and it's clear from IDC's comments the demand is driving US shipments. Outside of the US, it's still unclear exactly how well Google's low-cost laptops are doing. Most data from market research firms like IDC and Gartner focuses solely on Google's wins in the US.
