Do you want to avoid losing thousands of dollars in electronics? Surge Protectors are not just for computers.  It is a smart idea to have all of your electronics plugged into a surge protector.  Most electronics are sensitive to surges in power and more than one person has been known to lose thousands of dollars in electronics during a thunder storm.  For your desktop, a UPS is strongly recommended as it protects your PC from surges and brown outs, keeping it running if you lose power for a minute or two.  Nothing is worse than having a sudden drop in power and losing everything you have been working on.
