Some people heard that Windows Vista is bad, is not good, is resource consuming, etc and they don’t even want to try it.

Microsoft made an experiment: they asked people to write their opinion about Windows Vista, then asked them the opinion about “the new Windows” named Mojave (actually it was Vista with another name) and all of them were impressed ;)

Look what happened when they were told that Mojave is actually Windows Vista: http://www.mojaveexperiment.com/
