Well are they? What is the likelihood that a nuclear or non-nuclear EMP is going to destroy society? And if one does, will you really care if your laptop/cellphone/mp3 player still work? I just don't see EMPs as being a major concern when it comes to preparing for emergencies. I'd rather spend my time and resources on contingencies that I'm more likely to encounter.
