There's nothing wrong with providing simple ways to perform complex tasks, however, in certain situations simplicity has to make way for more appropriate tools. Windows 8, just like it's predecessors, provides both environments. For those less technical users, there's Metro style, as well as familiar desktop applications. However, quite often, performing more complex tasks, is either not catered for within the GUI or where there is, it can be severely limited. In these situations, making use of the Command prompt or Powershell is the best alternative.
