I've been thinking deep into this, and I get different opinions from many people, some people say you shouldn't upgrade to SP2, and others say yes.
The people that say no say it because they think it's another way for Microsoft to put a lock on you. The people that say get it say it because it blocks popups well.
Well... I use Firefox, and that's not much of a reason. The biggest reason would be for the security, however, if I've got Norton Anivirus and Internet Protection 2005, do I have anything at all to gain from SP2?
I didn't do much research into this. See, here is the real deal (or maybe not, you'll never know), my freind doesn't have entirely legal files on his computer, and he wants to know if he can upgrade and if Microsoft will put the pinch on him. I don't think they can really do that, but I've heard from too many people that they can.
