The shortest human read- and understandable answer to this poorly written bait article is: Mac OS is designed to run on only x, y and z hardware configurations whilst Windows is designed to run on the complete alphabet (a to z) of hardware configurations. This allows the developers of the former to have total control of the hardware and build specific workarounds, instructions and such as they know it will only run on that hardware. Windows, however, can be licensed to any hardware manufacturer. "It just works" (kinda) but that comes at the price of poor battery performance (and other things) as it isn't (and can't) be optimized as well as Mac OS.
