MS Window version 8 "User Experience"
I have used many versions of Windows for 20 years before it was overhauled into a phone OS for power hungry devices. It used to be a very interesting, and significant product, it was actually a general purpose Operating System that supported many windows at the same time, and was useful for many general purpose computing tasks.
Now when one of my friends or customers calls in desperation and says, "I just bought a new computer with Microsoft Window version 8, and I can't get it to do anything" I say, "Calm down, that is normal, neither can anyone else, bring it back to the store"
