Writing at Techpinion, John Kirkland reports:
Over 40 million of those 80 million Mac users are running the latest Mavericks operating system. That’s a 51% adoption rate, the fastest PC adoption rate in history. By way of comparison, after two years, Windows 8 adoption is at 14%.
This has as much to do with price as anything. Apple’s last OS X upgrade was free. I paid US$40 to get a special price when upgrading from Windows 7 to Windows 8.
Nevertheless, Apple’s engagement is vital. No other tech company comes close to getting the same level of buy in.
