There is an hilarious story that “8” will have a different user interface because of an 11% drop in usage of the “Start” menu. What’s wrong with this picture? The 89% of users still using the “Start” menu. Are the lunatics running the asylum? Yes.
This goes against the old tenet of “If it isn’t broken, don’t fix it.” We see this repeatedly in IT, change for the sake of change rather than better performance or efficiency. I would bet that 11% drop in usage is probably swamped by the increase in uptime and the time spent in the browser these days… Think of it. If you leave your browser running forever and a few applications running forever, do you really need to start anything?
