Plus there will come a time when MS windows update will insist on installation of SP2. MS issued a program to defer the SP2 update, I think that was a 90 days at a time. I also believe that it was mentioned that come March/April 2005 even that would not stop SP2 being offered as a critical update. You can of course choose to ignore it as you have.

Virtually all of the major e-newsletters after having suggested people hold off on SP2 now recommend it.
