I found this very interesting topic of the typical MS error in OS design and UID:
Mixing the two metaphors on the same screen completely undercuts Microsoft’s basic idea.

It’s like driving a car that has both a steering wheel and a joystick. Instead of giving users a tablet and a PC that you can jump between, Microsoft is at risk of giving users an awkward combination of the worst of both worlds. See more
