Business users killed Win8 before the official release by saying they had no interest in it. This is what happens when a company tries to create one IS experience to bridge desktops and tablets. There is a very valuable lesson here for Apple that they should make their products work together but not follow the path to destruction with a common OS that MS just took.
----------
HP tried the touch desktop years ago. Steve Jobs even joked about it in a presentation. "After the novelty wears off, the arms get tired." What in the world was MS thinking here?
MS needs to dump Ballmer and bring in a CEO who can push the company into the next real generation of computing with a total departure from the Win95 legacy of the registry with a new front end on it every few years. They also need to focus on what made their company and stop trying to me-too every product that comes along. They're no good at it and always years late.
All they had to do was make the other interface optional and provide a way to turn it off...even if it was just on the enterprise version. That was their mistake, and I hope they fix this simple omission in SP1.
