It was one of those things I always said I would get, but never quite got around to. A UPS/Surge Protection Board. I reckon it's a nice way to minimise the risk of loss when working on photographs and the power dips, goes off, or worse a storm surge. I just did a test on my notebook with the battery out of it and it works, gives about 15 minutes battery backup from the UPS, enough time to shut the system down before data loss. The model I got also has software which will auto shut the system down for you, so if you are away and the power goes off then things the OS will auto-shutdown. Although a little more than an average surge board, I reckon they are well worth the consideration
