The "Mojave Experiment"
Imagine if you had never seen or used Windows Vista, but hated it because of some negative things that you had heard or read somewhere. Then you were asked to evaluate a new Microsoft client Operating System, called "Mojave" and after the demo you absolutely loved it.
Then you find out that it is actually Windows Vista
