     This really cannot be overstated.

     I think there is a common misconception that backup power
supplies are there to give you an extra {few} minutes of power to
do an orderly shutdown, but our experience has not shown this.
Instead, it is there to filter out the 1 second power dropout
that seems to be much more common.  In addition, clean, sine-wave
power will do *wonders* to make those annoying port hangs and
such go away.  We have had several customers for whom serious
line conditioners have made a day-and-night difference.

     Many probably cannot imagine how much damage bad power can
silently do to your machine.
