  I'm happy with 5 to 10 minutes.  My main problem isn't extended power
outages, but 2 or 3 second outages that reboot the computer.  A few days
ago we had moderately high winds in the GTA that brought down tree
branches, which took down some power lines.  Twice that evening, the
lights flickered on-and-off in my condo, while hydro power got rerouted.
Those flickers would've rebooted my system.  The UPS did its job.  Each
time the lights flickered, I heard it click in and out.

  I have my LCD monitor plugged in to the UPS.  It's kind of hard to do
a manual shut down without a screen <G>.  The LCD monitor also provides
faint illumination while I run to the bedroom and fetch my flashlight.
