After reading some problems encountered here as well as those I have heard about from other places I am a little skeptical at best about installing SP3.
Basically from my understanding it's mainly a security patch to begin with . With that being the case as well as I try to keep things locked down here and perform regular PM's
I think I am safe without it :

On my weather server I am running no automatic updates..in fact no updates period! I will push them across the network if I really have a need for them. It seems like a lot of the M$ products want to phone home way too often and
provide Redmond or somewhere with a lot of info they don't necessarily need access to. I don't have anything to hide but it's just the principles I guess.
It does make for a bit of a problem especially when the one member had to reformat and re install the OS! Hopefully none of the rest of us will have to endure that...from an update anyway LOL!
