APC makes GREAT UPS's and have good support. I once blew out an APC by
miswiring a switch on a computer (don't ask). I called tech support,
they agreed that what I told them had happened shouldn't have happened,
and shipped me a new UPS for free, without any hassle. From that point
on, I swore I'd go APC first.

Not that I know of...there's daemons you can install for that purpose,
though.

Generally you need to add up your power requirements and match the load
to the UPS's power rating.

Today it's common to have a USB interface.
