We all know that WindowsXP Service Pack 2 has better security than its predecessors, it feqatures a pop-up blocker that has already been beaten, a security centre that is just annoying as well as program execution prevention - which makes it harder to run the programs you want.
Joking aside, the upgrade is definatly recommended for all users of WindowsXP, security has recently become a big issue as I guess people have finally become fed up of not only being infected by viruses, but just recieving them. With my narrowband internet connection, checking my mail is no longer a simple process, I have to download half a meg of viruses everytime I check my mail, bizzarely all coming from osnn mail accounts that don't exist. So upgrade people!!
The WindowsXP SP2 Performance review shows that for general use it is neither better nor worse than service pack one, but for gaming, perhaps due to the addition of DirectX 9.0c (somehow?) performance in certain applications, such as Splinter Cell, Unreal Tournament and (erm) 3DMark 2003 have been much improved, so that will hopefully tip the scale for you if you haven't taken the plunge already.
