The other problem is very long conductors, such as power lines, and cable TV and phone lines. The induced voltage and current from an EMP is proportional to the length of the conductor. Since these lines can be miles long, a huge spike would be generated on the lines, enough so that even devices without sensitive electronics could be damaged or destroyed.

I assume this part you're talking about a power surge. I use decent surge protectors in my house and I would assume that most high value and logistical targets would also use some sort of surge protection, at least at a minimum level. So that issue could be generously alleviated. Of course it wouldn't solve all of the problems but anyone can protect their electronics from a power surge.

Except in the '70s, the power went out in NYC because of a solar flare that screwed up Canada's power lines.

And then, nobody's electronics worked because there wasn't any power.

But hey, that's just history.
