If Microsoft was selling cars, they would insist that you know how to rebuild your transmission but NEVER tell you how to shift to drive the car. If that is not bad enough, they have to show how many different ways you can rebuild that transmission. Another words, totally confuse the user.
There must be one good way of doing things and Microsoft should be able to explain how to use the tools. If I need to know how the tool works, in order to use it, then I might as well build my own.
