Out of curiosity: why is it so extensive to implement? From my 
understanding (I'm currently working with partition tables at work) GPT 
should be simpler to handle than MBR. Or is this because it needs to be 
implemented in a Windows compatible way? If so what did they change 
there to make implementing GPT such a "problem"?
