This is one of the oldest asked questions. Here is my take on the whole thing.

Turn the fucker off when you're done using it. Why you ask? Well, for starters, what if you weren't home, or worse yet, asleep and your cooling fan took a shit or something like that and the fucker started to burn. Now what?

...or, there's a lightning storm in the middle of the night and you get a nasty surge that the protector fails to stop. You do have that cable protected, don't you?

Also, turning it on and off probably isn't the best thing for it but thats only if you own the same computer for 20yrs!! I turn everything off (modem included) and haven't had a problem in 5 yrs.

Don't be lazy, turn it off.
