Windows XP SP2

I have heard mixed reports about XP SP2. Some people I encounter swear they will never install SP2.

One employee from IBM told me they were not allowed to install SP2 on their Thinkpads.
With all that said, I have not really encountered any problems. Sure, when you install it, there is an annoying icon that appears by your clock saying "Meltdown imminent." However, once you get it installed and it settles down, I can't really see a reason for it not being installed.
SP2 does affect the general handling of the browser, including blocking pop ups, preventing code execution etc. These annoyingly unfamiliar events do tighten security for the sometimes unaccustomed end user. So as a developer, you need to be aware of these changes. However, remember that a system that runs fine on 2000, will not necessarily run the same on XP SP2.
Microsoft lawyers were making great claims of SP2 being attack proof, which certainly made me raise an eyebrow. However, I am sure it helps to keep the Gremlins at bay. It certainly creates another barrier.
