I would disagree with the comparison to New Coke. Drinkers of New Coke plain just didn't like it and there was nothing Coke could do to fix the product itself, so they had to revert to a different formula.
Windows 8 is more like the recent J.C. Penney disaster. Microsoft brought out this new version of what they think an operating system should be like, and ignored what their customers were telling them. Windows 8 can be fixed, Microsoft just needs to be willing to listen to their customers. They can start by making Metro an optional GUI overlay that can be enabled by the user - and not the default GUI. They can make Aero an optional GUI theme that can be enabled. Of course no one will get fired at Microsoft over this debacle like the JCP CEO did (except Steven who tried to stop the Windows roll-out). Microsoft should roll out a service pack for Windows 8 that takes care of these issues.
Baloney. Teaching to the test is exactly why we have so many MCP and MCSE paper professionals in the IT world that don't know jack. All they know is theory and they don't have any commonsense diagnostic skills to track down root causes of problems. They're the ones who reformat and ask questions later.
Teaching to the test teaches children one-dimensional thought processes. That makes them ill prepared for the real world where all kinds of screw ball curves are thrown at you and the text book way to solve an issue may not be the best or most efficient way to solve the problem.
Real computer scientists don't comment their code. The identifiers are so long they can't afford the disk space.
