It still shows SP3 on MS's site *shrug*
Never understood the compulsion to jump on a new service pack right after its released
most times it just borks your machine as MS Service Packs are renowned for being loaded with bugs.
I tend to wait a few months for them to work out the kinks...
Oh wait... no go ahead just make sure to report all your bugs and crashes ... that way when I get it, it will be more stable
