It runs OSX. That's it. Everything else, innovation (ex: Razer Core, Surface Studio), power (Kaby Lake, nVidia Pascal graphics), design & build quality (XPS, Razer, even Xiaomi!), flexibility (2-in-1's, touchscreens, MS Surface Book), price, etc., can be matched or surpassed in the PC world. And considering you are saving hundreds for similar or more powerful specs, it makes switching to Windows 10 a compelling case.
