     I have heard of UPSes which run continuously, and enjoy the
advantage of zero switch-over time.  But the inverter in a switching
UPS only has to run for the 20 minutes or so that the batteries last,
rather than continuously, so the components can be smaller, lighter,
and cheaper.  It'll run cooler, too (at least until the power goes
out :-).
