I've read a number of blog posts concerning power outage woes. Several years ago, our new computer was nearly destroyed by a daily loss of power. My late husband went to our local office supply store and picked up a battery back-up.
The brand we purchased is the APC Power Chute. Whenever the power goes off even for a few seconds, the battery kicks in so you can power down the computer in a safe manner. The battery lasts about 3 years, so it's economical.
