i lost a $3000 phone system earlier this year with gas discharge suppressors on the phone lines and UPS on the power cord.  if mother nature is gonna get you, she's just gonna go on and do it no matter what protection you have.

wow that blog post reference is fascinating.  And VERY detailed.

I think that what it means is most houses are radically
under-protected from lightning.
    

Fortunately, direct lightning strikes on homes are rare. That webpage is 
written for ham radio operators with big-ass antenna towers that need 
lightning protection. As you can imagine, big-ass towers (BATs) make 
excellent lightning rods. :)

I once visited a customer who had lightning strike the utility pole 
outside his business. The pole's grounding cable properly sent most of 
the current harmlessly into the ground, keeping most of his equipment 
from getting fried.

But not all of it stayed in the ground: he had ungrounded copper lines 
running between buildings. The current happily followed these lines 
right into his computers. Lucky for him, the lightning merely blew out 
the modem cards and not the PCs in which they were installed. If he had 
a simple grounding block on those lines, he would have not even noticed 
the strike (a *direct* strike on his building would've been another 
story, though).
