I agree, solar storms only threaten our electronics. What concerns me is, how people would react after such an occurance. Worst case scenario, it could get very ugly.
Things tend to get ugly, when people start to panic, that's a very true statement right there. This said, it's all manageable, from a purely material point of view. It might be hard for a bit, but not the doomsday that some are saying it will be.
