Suspenders and a belt.

We have the applications to think about too. It's all well and good to say 
they should be able to recover gracefully, but to those of us supporting 
things we didn't write, having the system shut down cleanly just might save 
me hours of work later.

I have a perfectly good serial-only Best 1.8kva from 1996 that gives me 3 
hours of runtime, with monitoring. I should throw it out just because it 
doesn't have USB ?
