Windows XP Service Pack 3 Good, Vista Bad

Oh look, yet another reason *not* to upgrade to Vista:

The third service pack for XP gives you all the Windows XP performance updates, security updates and hotfixes that have been released since Service Pack 2 came out way back in August 2004. While Service Pack 3 may not be as big of a change as Service Pack 2 was, there are some noteworthy features from Vista that have been included in this release. Namely, NAP, a policy enforcement platform for limiting network access to secure machines, “Black Hole” Router Detection, a cryptographic module for the kernel and a new Product Activation module allows you to install XP without a product key.
