I tried SP2, and I have no idea what all the fuss is about.
It's got some really annoying firewall that makes no real difference to crackers.
SP2 is absolete. If I wanted a firewall, a browser with an integrated pop-up blocker and a bloated media player in Windows XP, I'd download ZoneAlarm, Firefox and RealPlayer. It's actually better that way and securer that way.
Because really, that's all there is to SP2, a crappy firewall, a wannabe browser and a bloated media player.
