Through the U.S. consumer retail channel, Macs notebooks reached rather shocking milestone during first half 2015, according to data that NPD provided to me today. You can consider this a first, and from lower volume shipments. By operating system: OS X, 49.7 percent; Windows, 48.3 percent; Chrome OS, 1.9 percent. That compares to the same time period in 2014: OS X, 44.8 percent; Windows, 53.1 percent; Chrome OS, 2.1 percent. The data is for U.S. consumer laptops.
While data junkie journalists or analysts often focus on unit shipments, revenues, and subsequently profits, matter much more. Looked at another way, Mac laptop revenues rose by 10.9 percent during the first six months of 2015, year over year, while Windows PCs fell by 9 percent, and Chromebooks contracted by 9.5 percent.
