Regarding unannounced power outages, I got hit with a good one a while ago.
The power cut cleanly, but when it came back on my incandescent lighting
flickered at what looked like a 10hz rate, cycling from off to bright for
several seconds at this guestimated rate.  PG&E lost a power cable, they say.
At any rate, my Mac & hard drive survived just fine (they were on when the
power failed & I foolishly forgot to turn them off).  The power amp in my 
stereo failed spectacularly however.  I *always* left it on.  Alas, the 
bridge rectifier failed and raw AC ran amok through the drive and output
transistors.  What a stink!  The message here is that at least in one case
a MAC and a hard drive survived a gross insult that a less intricate piece of
gear couldn`t endure even though it had several safety circuits built in.
