I have seen 10,8 machines getting security updates since 20.9 launched.

The "Apple Tax" is totally outdated. Usually stated by people who haven't looked at Macs in more than a decade. If you build a machine spec for spec against a Mac prices are competitive. TCO for Windows is higher when you add in cost of antivirus, OS updates, and other software that just comes on the Mac. Why OS X? Unix under the hood and a nice OS. I have an imac with extra displays, mixer, studio monitors, all the goodies. The imac can do anything another PC can and then some. Some people just feel the need to be haters.
