Last time I often find my home PC powered off when I get back from the work. This is quite inconvenient cause I used to read my mail using mutt over ssh, so always login to my home PC remotely. Small power drops, I thought and bought UPS Powerman Optima 500VA to fight them.
However, returning from the shop with my new purchase I found an announcment on the doorway about planned power trunk replacement and power being turned off each day long till the middle of July. Needless to say that my UPS will not help here at all, but at least the PC will shutdown properly.
