For example, if you had a front projector (or projector TV) the lamp life can be severely shortened by on-off cycles that don't allow for proper cooldown. A UPS can really help and is recommended for all projector systems. The only disadvantage is that batteries have a certain lifetime (3-5 years) and therefore there is an expense involved. In addition, a UPS capable of handling all your equipment will be more expensive than the minimal types often seen for $40-$50. I use a UPS on my Home Theater system and on my computer.

The main advantage is the one you mentioned, that in the event of a power outage you can turn of the equipment so that you can control when it comes on. This is especially important for brief outages (ON-OFF-ON in a few seconds) which can be damaging to equipment because these often are accompanied by over and under voltages. Another advantage that is not well known is that besides protecting against power outage, a good UPS will shut off if the line voltage goes below or above normal by more than a set amount. It is these lower or higher than normal voltages that can really damage the equipment. I know of no disadvantages to using a UPS on your equipment, and there are advantages over a surge protector.
