Well..I DO NOT use SP2. As for MS not supporting you unless you have SP2 installed..this is not true. Windows update will NOT work but, you can still download & install patches from technet-(http://www.microsoft.com/technet/Downloads/default.mspx). I have run into several issues with SP2. The main "issue" is unexplained "slowness" when opening folders (pretty sure it has to do with indexing). As for increased security..bah.. the MS firewall is pathetic...get a real firewall if you think you need one. IMHO..wait for SP3.

It's a shame stupidity isn't painful.
