As most of you are aware, article 334.10 changed drastically in the 2002 NEC. NM cable can now be used nearly anywhere that is not required to be combustible construction (types I and II).
Example: The 150,000 square foot home depot or Lowes or super walmart down the down the street. Are these buildings required to be non-combustible? Beleive it or not, the answer is probably no.
There are many buildings that meet the criteria for an "unlimitted area building" because of fire sprinklers and large property frontage. These buildings are type "VB" construction, meaning that they could be built out of wood!
If you are in the business of designing "as-build" electrical installations, this could mean the difference of winning the bid. Make sure to check with the building department about types of construction before you commit, however.
BTW: keep in mind other aspects of the code such as health care and places of assembly, to name a few.
